产品描述:
The product CSB-E15979h is a sandwich ELISA kit developed to measure concentrations of human CD68 in serum, plasma, or tissue homogenates. This assay uses the sandwich enzyme immunoassay technique in combination with the enzyme-substrate chromogenic reaction to quantify the analyte in the sample. The color develops positively to the amount of CD68 in samples. The color intensity is measured at 450 nm via a microplate reader.
CD68 is predominantly expressed in late endosomes and lysosomes of macrophages and is widely considered to be a specific biomarker for macrophages/monocytes. Overexpression of CD68 is indicative of macrophage/monocyte dysfunction and hyperproliferation. Furthermore, CD68 is identified to be a useful biomarker of rheumatoid arthritis and Hodgkin's lymphoma. CD68 alone or in combination with other cell markers of tumor-associated macrophages showed a good predictive value as a prognostic marker of cancer patient survival.

功能:Could play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. Binds to tissue- and organ-specific lectins or selectins, allowing homing of macrophage subsets to particular sites. Rapid recirculation of CD68 from endosomes and lysosomes to the plasma membrane may allow macrophages to crawl over selectin-bearing substrates or other cells.
