  • 产品描述：

    The human milk fat globule-EGF factor 8 protein (MFGE8) Elisa kit is suitable for the quantitative measurement of human MFGE8 in serum, cell culture supernates, urine, or cerebrospinal fluid (CSF). This assay employs the sandwich enzyme immunoassay technique and enzyme-substrate chromogenic reaction. The color develops positively to the amount of MFGE8 in samples. The color development is stopped and the intensity of the color is measured. This kit displays many advantages, including high sensitivity, strong specificity, good linearity, high precision and recovery, as well as lot-to-lot consistency.

    MFGE8 is a multifunctional glycoprotein that is found in lacteal glands and milk fat globules and contributes to connecting αvβ3 integrin on phagocytic macrophages with phosphatidylserine on apoptotic cells thus enhancing engulfment of apoptotic cells. This process is essential for maintaining the host immune system under physiological conditions. In addition, MFGE8 also directly regulates various cellular functions, such as attenuating inflammation and healing of injured tissues. MFGE8 has been demonstrated to have anti-inflammatory and regenerating roles during intestinal inflammation. Studies have recently identified MFGE8 as a novel and outstanding modulator for vascular aging via targeting endothelial cells (ECs) and vascular smooth muscle cells (VSMCs).
