Biotin anti-human CD107a (LAMP-1)

CD107a, also known as Lysosome-Associated Membrane Protein 1 (LAMP-1) or LGP-120, is a 110-140 kD type I membrane gly­coprotein. Mature CD107a is heavily glycosylated from a 40 kD core protein. It is expressed by activated platelets, acti­vated lymphocytes, macrophages, epithelial cells, endothelial cells, and some tumor cells. This molecule is located on the luminal side of lysosomes and has been suggested to play a role in the protection of lysosomal membrane from lysosomal hydrolases. Upon activation, CD107a is transferred to the cell membrane surface. It plays a role in cell adhesion and regula­tion of tumor metastasis, and mediates autoimmune disease progression. CD107a is a ligand for galaptin and E-selectin.
