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
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
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
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
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
Glucose-6-phosphate dehydrogenase fluorescence spot test
In the presence of glucose-6-phosphate (GbB) and NADP, glucose-6-phosphate dehydrogenase (G6PD) is able to use NADP to reduce to NADPH, which does not fluoresce
