PARAFORMALDEHYDE

OH(CH2O)n H F.W. Average: 600 CAS #30525-89-4

EM grade, purified
A fast penetrating E.M. fixative in combination with other fixatives.

Paraformaldehyde is the condensation product of methylene glycol, a substance not so far isolated in its pure form; it is a white solid with a formaldehyde content between 78 and 98% and is supplied either as a Prill or Granular ‐ ask. All forms contain more than 95.5% paraformaldehyde content. The Prill and Granular forms are small, free‐flowing, dust‐free beads, the most desired by EM users. A fast‐penetrating EM fixative used in combination with Glutaraldehyde, Acrolein, and Osmium Tetroxide.

Poly-L-Lysine slide
POLY-L-LYSINE SOLUTION

Poly‐l‐lysine treated surfaces offer better adhesion for histological sections and other thin specimens.

0.1% w/v aqueous solution; preservative. Adhesive for tissue sections on glass slides. Immunohistochemical techniques, gold labelling, microwave procedures.


Method: Apply 15μl of 0.1% Poly‐L‐Lysine solution the surface of slides or vessels required to gain better adhesion; then leave at room temperature for one hour or more. Longer times, up to overnight also work well.

Remove the solution and rinse the treated surface twice with distilled water.

To dry, stand surface vertically. The item is then ready to use. Some users prefer to keep the surface wet until ready for use.

POLYESTER WAX
A synthetic polyester wax with a very low melting point (37°C). Invented by Dr. H.F. Steedman, as a ribboning embedding medium. Its main advantage over paraffin and ester waxes is its low melting point, which reduces tissue hardening, shrinkage, and eliminates the need for infiltration ovens.

The wax is soluble in most organic solvents, including alcohol, ethers, esters, ketones and hydrocarbons. The wax is water tolerant, almost opaque, and sections easily. No electrification of ribbons occurs during sectioning. Sections of 2 microns and more may be cut at room temperatures between 10 and 22°C. It is advantageous to keep the wax in its solid state prior to use.
