Histology Reagents
Electron Microscopy Sciences Acetone: Xylene 500 ML
Used in Brown and Brenn Method for gram positive and gram negative Bacteria.
Also see the Taylor Modification of the Brown and Brenn +/- technique noted for the varying differentiation available. Over-differentiation in the B&B sep 6 is a problem with some sections; run the control slides at varying rates to determine the amount for the specific organism.

Electron Microscopy Sciences Glutaraldehyde Aqueous 70%, EM Grade 2 ML
OCHCH₂CH₂CH₂CHO F.W. 100.12
Aqueous glutaraldehyde, the universal fixative for electron microscopy, is purified to EM grade from commercial grade by "all-glass vacuum-distillation". It is the highest possible quality, free from polymers and other contaminents. Each lot is assayed prior to shipping assuring consistent purity and the highest possible quality.
If stored properly, our Glutaraldehyde has a very long shelf life. EM grade aqueous glutaraldehyde, stored in volumes greater than 100 ml, with repeated defrosting and recapping, will polymerize in time, producing an absorption peak of 235nm rather than the 280nm of pure EM grade. The presence of polymerized glutaraldehyde greatly reduces its efficiency as a cross-linking agent, preventing proper fixation. For this reason, we provide 10 ml ampoules sealed under dry nitrogen and 100 ml bottles that are kept refrigerated until it is shipped.

Electron Microscopy Sciences Glutaraldehyde 25% Aqueous Solution, 111-30-8, MFCD00007025, 10 mL ampoule
Formula: OCHCH2CH2CH2CHO, MW: 100.12. After glutaraldehyde has been purified to EM grade, it has a high risk of polymerizing if it is not handled properly. Electron Microscopy Sciences takes special precautions to assure a polymer-free, pure glutaraldehyde. 4 to (-18)°C.
Polysciences, Inc. Soft Nail, 250 mL
Made for very hard complex keratinized hair, nail and skin samples common in Mohs Histology laboratories. Hair, nail and skin samples that have been processed tend to flex and turn becoming difficult to cut and hold on slides for staining.
