In Situ Hybridization Fixative Solution
In histopathology, tissue must be fixed in time and effectively before subsequent embedding and sectioning. The function of tissue fixation is to maintain the inherent morphology and structure of tissues and cells, prevent bacterial corrosion and autolysis of tissues and cells, preserve intrinsic substances in cells, coagulation of proteins in cells, minimize or terminate the reaction of endogenous and exogenous enzymes, so that cells or tissues basically maintain the same substances as life, but also make tissues harden, which is convenient for repair and cutting of thetissue.

Alcian Blue Dye Solution
Alcian blue is any member of a family of polyvalent basic dyes which belongs to cationic dye and initially was used for dyeing textile fibers. This dye is soluble in water and has a blue color due to the presence of copper in the molecule. It is a dye specific for acid mucins, which can bind to acidic groups to form salt bonds and stain the tissues with compounds containing anionic groups, such as acid mucosubstances and acidic mucins.

Masson Tricolor Staining Kit
Masson's three-color staining method, also known as Masson staining, is a more classic collagen fiber staining method. This method makes use of the different permeability of anionic biological dyes and molecular weights in connective tissues. Dyes with small molecular weights can easily penetrate tissues with dense structures and low permeability, while dyes with large molecular weights can only enter tissues with loose structures and good permeability, so different tissue components present different colors.

Eosin Y Solution (Alcoholic)
Eosin Y is an acidic dye used in histology for staining cell plasma. The basic principle is that eosin dissociates into negatively charged anions in water, which can bind to the cationic amino groups of proteins in the cytoplasm and give the cytoplasm a red color.

TSAPLus Fluorescence Double Staining Kit (Green IF488+ Red IF594）
TSAPLus fluorescent double staining kit (IF488+ Red iF594)of this product is suitable for double immunofluorescence staining of paraffin sections, especially for double fluorescent immunolabeling of primary antibodies from the same source, and also for double fluorescent immunolabeling of antibodies from different sources. The main principle is based on Tyramide signal amplification (TSA), hereinafter referred to as TSA technology.
