    AAF fixative instructions ? Key words: fixative, buffer, biochemical solution, Qiaoyu biological reagent Product introduction : The purpose of fixation is to preserve the original morphological structure of cells and tissues. The fixative can prevent endogenous lysosomal enzymes from autolysis of their tissues and cells, and inhibit the growth of bacteria and molds. The immobilizing agent inactivates the enzyme by coagulation, formation of an added compound, and the like, thereby changing the internal structure of the protein. The fixative physically changes the extracellular components of the nucleus. The living cells are wrapped in an impermeable membrane before being fixed, and the fixative can destroy the barrier, allowing the macromolecular substance to penetrate the membrane and escape. The choice of fixative is extremely important for tissue staining and immunohistochemical staining. Usually, several fixatives are mixed and formulated into a composite fixative, which can adapt to the preservation of various tissues and cellular components. However, there is currently no standard fixative. Suitable for the preservation of all tissues and cellular components. The fixative is mainly divided into an aldehyde fixative, a mercury fixative, an alcohol fixative, an oxidant fixative, a picrate fixative, etc., and is commonly used in formalin and alcohol in aldehydes. Ethanol. ? AAF fixative, also known as alcohol formalin mixed fixative or FAA fixative, consists mainly of ethanol (A), acetic acid (A), and formaldehyde (F), and has both dehydration effects. AAF fixatives are commonly used for rapid dehydration and fixation as well as rapid fixation of frozen sections. ? product composition: name specificat
