产品描述
This human phospholipidase A2 (PLA2) ELISA kit employs the quantitative sandwich enzyme immunoassay technique to measure the levels of human PLA2 in different samples, including serum, plasma, or tissue homogenates. The enzyme-substrate chromogenic reaction is also used to amplify the signal and quantify the levels of the analyte through the intensity of the colored product. The color intensity positively correlates with the amount of PLA2 bound in the initial step.
PLA2 plays key roles in multiple cellular responses, including phospholipid digestion & metabolism, host defense, and signal transduction. PLA2 catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid (AA), a precursor of eicosanoids including prostaglandins and leukotrienes. PLA2 is a key enzyme in the regulation of lipid mediators of the inflammatory process. Evidence has shown that PLA2 is involved in all stages of pathogen encounter, from the initial signaling to the uptake, degradation, and presentation of the antigen.

线性度
| To assess the linearity of the assay, samples were spiked with high concentrations of human PLA2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. |
