The antibody was purified by affinity chromatography and conjugated with APC under optimal conditions. The solution is free of unconjugated APC and unconjugated antibody.
CD151, also known as PETA-3, is a 29 kD protein member of the tetraspanin family (TM4SF). As other members in the family, PETA-3 is composed of two extracellular loops (one larger than the other), four transmembrane domains, and two cytoplasmic tails. Also, as other members in the family, CD151 is involved in cell adhesion, migration, and tumor cell metastasis. PETA-3 is expressed by many different cell types such as immature hematopoietic cells, megakaryocytes, platelets, keratinocytes, epithelial cells, muscle cells, Schwann cells, and vascular endothelium. On the cell surface, PETA-3 associates with CD9, CD181, and the integrins α3β1, α5β1, and α6β4.
