Non-specific esterase staining assay
Nonspecific esterase (Nonspecific, esteras. NSE) staining method can be divided into three categories: neutral non-specific esterase, acidic non-specific estera
alkaline phosphatase staining assay
Alkaline phosphatase in cell tissues hydrolyzes the substrate (sodium naphthol a-monophosphate) in the action solution in an alkaline (PH 9.0-9.6) environment t
peroxidase staining assay
The peroxide E in the cell decomposes hydrogen peroxide to release O atoms, which oxidize benzidine and change it to benzidine orchid, causing the cell plasma t
Erythrocyte osmotic fragility test
This test is to determine the resistance of erythrocytes to different concentrations of hypotonic saline solution, this resistance is closely related to the rat
Cellular iron staining assay

Sudan black staining experiment
Sudan black B (SB) is a fat-soluble dye, which can be dissolved in the lipid-containing structures in the cell plasma, so that the lipids in the cytoplasm appea
Periodic acid-Schiff's reaction experiment
The principle of PAS reaction to show sugars is due to the polysaccharides containing glycol groups, under the action of periodic acid, oxidation to produce ald
hemolytic test
This test uses the patient's erythrocytes to cause hemolysis to occur after incubation in their own serum (containing complement) at 37°C due to acid productio
