Specifications for TM4SF1 Antibody, anti-human, REAfinity™


Clone REA851 recognizes the human TM4SF1 antigen, also known as transmembrane 4 L6 family member 1. TM4SF1 is a member of the tetraspanin family, which members are involved in signal transduction events, important for the regulation of cell development, activation, growth, and motility. It is reported, that TM4SF1 suppresses the expression of CD63 and CD82, two molecules that inhibit cell mobility. TM4SF1 is highly expressed in lung, breast, colon, and ovarian carcinomas. It is also found on some endothelial cells.
Additional information: Clone REA851 displays negligible binding to Fc receptors.
