Milk fat globule epidermal growth factor 8 (Mfge8) is a peripheral membrane soluble glycoprotein. It is liberated by several cells like macrophages. This protein is also termed as a phagocytosis “eat me” signal. It is predominantly expressed in lactating mammary glands.MFG-E8 has two-repeated EGF-like domains, a mucin-like domain, two-repeated discoidin-like domains (C-domains) and an integrin-binding motif (RGD sequence) in the EGF-like domain. This gene is located on human chromosome 15q26.
Immunogen
MFGE8 (NP_005919, 61 a.a. ~ 170 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.
Milk fat globule epidermal growth factor 8 (Mfge8) controls inflammation and immunity by mediating apoptotic cell clearance. It plays an important role in autoimmunity, neoangiogenesis and sperm-egg binding. Mfge8 also plays a major role in membrane vesicle secretion like budding or shedding of plasma membrane (microvesicles) and exocytosis of endocytic multivesicular bodies (exosomes).

Tumor cells secrete factors that modulate macrophage activation and polarization into M2 type tumor-associated macrophages, which promote tumor growth, progression, and metastasis. The mechanisms that mediate this polarization are not clear. Macrophages are phagocytic cells that participate in the clearance
