Analysis of PAF acetyl-hydrolase (Human) by ELISA (CAT#: STEM-MB-1114-LGZ)

Introduction

Platelet activating factor (PAF) is a biologically active phospholipid synthesized by stimulation of various cells. PAF is converted to the biologically inactive lyso-PAF by PAF acetylhydrolase (PAF-ah). PAF-AHs are located intracellularly and extracellularly (eg, in the cytoplasm and plasma). Plasma PAF-AH is highly selective for phospholipids with a very short acyl group at the sn-2 position and is associated with lipoproteins.




Principle

Enzyme-linked immunosorbent assay (ELISA) is an enzyme-labeled solid phase immunoassay technique. Its basic principle is to bind the antigen (or antibody) to the solid phase carrier, and the antigen (or antibody) and a certain enzyme link to enzyme labeled antigen (or antibody). During detection, the sample to be tested and the enzymic antigen (or antibody) react with the antigen (or antibody) on the solid phase carrier according to certain procedures, and then remove the unreacted part by washing method. After adding the substrate, the substrate is catalyzed by the enzyme on the solid phase carrier to produce colored substances. Through qualitative or quantitative detection of the amount of colored products, the content of the substance to be measured in the sample can be determined.
