Description

Reticular fibers are very thin and delicately woven strands of type III collagen. These fibers are not visible with the H & E stain but they react very well with ammoniacal and methenamine silver stains. This Reticulum Stain Kit is designed for the detection of reticular fibers in histological tissue specimens.

To make Working Ammoniacal Silver Solution: Using chemically cleaned glassware or virgin plastic ware add 10ml of Silver Nitrate Solution to 17 ml distilled water and mix thoroughly. Then add 1 ml of Concentrated Ammonium Hydroxide while mixing; the solution will turn light brown, and then become colorless. Add 10 ml of 3% Sodium Hydroxide Solution and mix thoroughly; solution should be colorless; if not, add Concentrated Ammonium Hydroxide drop by drop until no precipitate remains. To complete solution, add distilled water to obtain a total volume of 60 ml and mix thoroughly.
