Tannic acid, powder
Reagent / A.C.S. grade. Galloylglucose.
Tannic acid was introduced as a secondary fixative mixture with aldehydes for biological tissues, and also as a stain. Specimens treated with Tannic acid show increased contrast and more delineation of cell membranes.
A low molecular weight, Tannic acid (LMGG) galloylglucose (C14H1009)n, provides and overcomes the previous problems of unsatisfactory penetration, extraction, and precipitation when high molecular weight Tannic acid (C76H52O46) was utilized.
It works primarily as a mordant between osmicated structures and Lead citrate of the post-staining, revealing additional ultra-cellular structures and details better delineated.
