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
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
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
Cellular iron staining assay
Ferritin and ferritin (extracellular iron) in bone marrow and iron particles (intracellular iron) in naive erythrocytes interact with potassium ferrocyanide to
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
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
Indirect method for the detection of anti-human globulin test
The purpose of the indirect test is to check for the presence of free incomplete antibodies in the serum. First, Rh(D)-positive O-type (or the same type as the
