Mounting Media Basics

The main purpose of mounting media is to physically protect the specimen; that also includes anti-fadent components for fluorescent dyes. Mounting media are usually applied as a couple of drops onto the specimen, which is then inverted with a hanging drop onto a coverslip. The mounting medium bonds specimen, slide and coverslip together with a clear durable film. The medium is important to the image formation as it affects the specimen's rendition. Until recently the most commonly used general mounting medium was DPX (Depex), this has been replaced by Entellan.

Mounting media are often chosen for a specific refractive index (R.I.), which can enhance specimen details or make them invisible. Materials like glass become totally invisible if immersed in a solution of the same refractive index. Glass chips can be identified by their R.I. All common mounting media use an R.I. close to that of borosilicate glass (coverslips), but a minor change of R.I. can improve the visibility of particular specimens. Most microscopists use a general mounting medium - like Entellan, but for special requirements like water-miscible, different R.I. or a need for an anti-fadent (especially in fluorescent microscopy), search for a special medium is advised.

Do not use immersion oil on an uncovered slide. If in a hurry to view a specimen under oil immersion, mount the slip and handle the mount carefully, keeping it horizontal. Oil can be applied, but do not attempt to wipe it off until the mounting medium is cured - at least overnight or an hour on a hotplate or in an oven. Do not store mounted slides vertically for 2 days if cured at room temperature.

Slides should be stored in a dark (slidebox) and cool place to slow fading of stains. Except for some special stains and mountants, mounting media and stains will last for decades and deterioration is very slow.

CITIFLUOR™ ANTI-FADENT MOUNTING SOLUTIONS

These mounting media are designed to reduce the fading of the fluorescence of dyes used for labelling biological specimens.
In fluorescence microscopy, the fluorescence is stimulated by high intensity UV and/or visible light. Absorption of the light creates an excited state of the dye (usually a singlet state) and this leads to fluorescence. However, the excited state of the dye may undergo chemical reactions which lead to its destruction as evidenced by the fading or bleaching of the fluorescence and consequent loss of the image, or in the case of assays, a change in signal intensity during measurement.

There is no universal anti-fadent; due to the varied nature of biological material the fluorescence fading of fluorochromic conjugates is a complex process.
The general anti-fadents are AF1, AF2 and AF3. AF87 is a specialist immersion oil-based anti-fadent.

AF1 is an anti-fadent (anti-bleaching agent) contained in a glycerol PBS (phosphate-buffered saline) solution and is particularly useful for examining tissue sections.
AF2 solution contains the anti-fadent in glycerol which enables users to choose their own buffer.
AF3 which contains the anti-fadent in PBS solution, is particularly useful for examining live cells.
AF87 contains the anti-fadent in a nonfluorescent immersion oil. It is designed for those wanting to work at a high magnification. It is particularly useful for preventing the fading of such dyes as DAPI which have the unfortunate tendency to disperse in glycerol based mountant solutions.
CFPVOH is an aqueous solution of polyvinyl alcohol for use as a solid mountant. A few drops of the solution applied to your specimen and allowed to dry will produce a clear film.
AF100 is a solution of anti-fadents to be used with CFPVOH when fading of fluorescence in the polyvinyl alcohol is a problem. To prepare a CFPVOH solution containing AF100, add 0.1mL of AF100 to 0.9mL of CFPVOH. If more or less of the solid mountant solution is required, mix the reagents in the appropriate ratio. Once these solutions have been made up, they should be used within a period of days rather than months, since the solutions deteriorate on storage.

These products have a long shelf life, at least 2 years, and can be stored at room temperature. With an LD50 of >2000 mg/kg (rat) none of the solutions should pose a toxicological problem.

BIOMOUNT™ MOUNTING MEDIUM
Some mounting media oxidise rapidly upon exposure to air, forming carboxyl groups. This can be more pronounced when sections have been cleared in a solution containing aldehyde. It is sometimes observed that the immunogold/silver signal fades after a few weeks, or even in a shorter time, from sections that have been mounted with these media under cover slips. The silver is still present, but has formed translucent silver carboxylate salts. Visibility can be retrieved by removing the cover slip and washing in xylene and then immersing the slide in photographic developer, but this is a tedious procedure.
BioMount™ is a specially formulated mounting medium that reduces fading of immunogold/silver signals in sections on glass slides. It is suitable for resins as well as wax embedded sectionsof tissue. Store at RT.

IMMERSION OILS

Cargille was first to introduce PCB-Free immersion oils in 1972. Though all immersion oils are now PCB free, no other immersion oil meets FDA criteria; and Cargille's exceeds ISO, DIN and all instrument manufacturer's standards.

Minimum shelf life of these immersion oils is 5 years and can be twice that.

Blending Oils from the Miscible Group: The Miscible Group of immersion oils is A, B, NVH and OVH. Users can easily blend any two immersion oils from the Miscible Group to obtain an immersion oil with an intermediate viscosity while maintaining the optical properties common to both. Type 37 can be blended with type B.

All Cargille immersion oils are classed as low fluorescence, however, for work with weak fluorescence, types FF and LDF - see below - are required.

50mL is supplied in a high density polyethylene bottle with a pointed, twist closure suited to place single drops onto slides. For refills and large users these oils are available in larger glass bottles and in the original 1 US gallon (3.785 litre) steel cans with resealable pouring spout. We stock the gallon container for type B only, but will procure other types on indent within three weeks.

For Normal Light Microscopy use Types A and B.
Elevated Temperatures (>23°C to 37°C): Use Type 37.
Inverted, Inclined, Projection, and Long Focus Instruments: Use type NVH or OVH. the greater the gap between the cover glass and objective, or between the slide and condenser, the more desirable high viscosity becomes. Their very high viscosities give excellent results for these applications.

Fluorescence Microscopy: Extremely low fluorescence is achieved by Type LDF and Type HF.

Types A & B Immersion Oils
These two types practically vary only in viscosity and they are interchangeable and miscible with each other for intermediate viscosities. Produced in larger quantities than other types, Types A and B are the most economical. The deciding factor in choosing between them is the optimum viscosity for your particular application.

Type A, at 150 centistokes, reduces any tendency to trap air, especially helpful to beginning students. Air bubbles cause image degradation. Also Type A is less sticky and easier to clean up.

Type B, at 1250 cSt, is thick enough for viewing multiple slides with one application. This saves time during batch processing. Type B is the most used of these immersion oils. For a greater gap between cover glass and objective, (or condenser and slide) type B is more desirable.

For horizontal, inverted and inclined instruments and projection equipment, Type NVH with high viscosity of 21,000cST or Type OVH with a viscosity of 46,000 cST, (about 3 times that of honey) should be used. These types combine high or very high viscosity with "normal" refractive index properties. The greater the gap between the cover glass and objective, or between the slide and condenser, the more desirable high viscosity becomes. Their very high viscosities give excellent results for these applications.

TYPE 37 HIGH VISCOSITY IMMERSION OIL

Elevated Temperatures (>23°C to 37°C)

Elevated temperatures can be due to substage illuminators, "hot stage", or other causes - ideal situations for Cargille Immersion Oil Type 37.
Immersion Oil Type 37 is useful for microscopic studies at body temperatures or when high room and stage temperatures may approach 37°C. Developed specifically for working at human body temperatures, Type 37 has a refractive index of 1.515 and a viscosity of 1250 cSt at 37°C solving the problem of image degradation above the standard calibration temperature of 23°C. Since the refractive index/ temperature relationship is inverse, increasing temperature significantly reduces the refractive index and lowers the viscosity of immersion oils. Cargille resolved this problem with Type 37 immersion oil. For any Elevated Temperatures (>23°C to 37°C) use Type 37. Users can blend for their own working temperature; blending Type B, with a viscosity of 1250 cSt at 23°C with Type 37, 1250 cSt at 37°C maintains a constant 1250 cSt viscosity and optical values and places the temperature of calibration proportionally between 23°C to 37°C.

IMMERSION OIL, LOW FLUORESCENCE, TYPE LDF

Fluorescence Microscopy

This is in most regards our best immersion oil for fluorescence microscopy. It has extremely low background fluorescence (Cargille # 1-2). It has excellent optical values of refractive index (1.515 at sodium yellow 5893 angstroms and 1.518 at mercury green 5461 angstroms) and dispersion (41.3 for Abbe υD) for a sharp image. It has a medium viscosity of 500 cSt. It has an odour, (1-bromonaphthalene), that some people dislike.

FLUORESCENCE-FREE IMMERSION OIL, TYPE FF

By Cargille

This oil is halogen free, has no odour, and is also nearly free of background fluorescence (Cargille # 1 max.). For optical properties its refractive index is 1.479 at 5893 angstroms which is lower than the ideal 1.515 so image sharpness is less, but probably not noticeably. It has a low viscosity of 170 cSt.

REFRACTIVE INDEX LIQUID SERIES

Cargille Refractive Index Liquids have become standard items in many laboratories as their applications have expanded from routine mineralogical identifications and quality control. New and broader uses in many more fields such as chemicals, engineering, medical, forensic, optics, and instrumentation are continuously discovered. Many special requirements for specific applications have created a need for more technical data, new formulations, extended ranges, smaller increments and higher degrees of precision.

Since 1942, Cargille Laboratories, Inc. has been filling this growing need. And today, the largest and most comprehensive assemblage of refractive index liquids - over 250 stocked items - are available for science, industry, medicine, and education. For specialised and unusual applications, many more can be formulated and others are routinely researched in anticipation of new needs.

Chlorofluorocarbon (CFC) components used in some Cargille optical liquids have physical properties that are harmless to the ozone layer, unlike those found in refrigerant gases, propellants, and solvents, which are destructive. The components used by Cargille Laboratories have vapour densities ten times that of air, are relatively nonvolatile, and have boiling points at least 100°C higher than the highest-boiling CFC of those listed for removal from commercial use by the Montreal Protocol.

Applications

Cargille Refractive Index Liquids have a broad range of applications in diversified fields. The following table briefly illustrates some of the typical areas of use.
