Technology
A type of homogenous immunoassay in which sample is applied to a reagent mixture of enzyme-labeled ligand, antibody, and substrate. Substrate binding to enzyme leads to inactivation and unlabeled-ligand in the sample can be quantified by colorimetric analysis.
Technology
A test that uses Coombs' reagent to detect the presence of anti-erythrocyte antibodies in serum.
Technology
This is an all-round useful stain for many things, including glycogen, mucin, mucoprotein, glycoprotein, as well as fungi. The reaction is based on the oxidation of glycol group to aldehydes by periodate. The schiff's reagent selectively stains the aldehydes to a rose pink color. PAS is useful for outlining tissue structures--basement membranes, capsules, blood vessels, etc.
