The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions. The solution is free of unconjugated biotin.
Lymphotoxin-α (LT-α), also known as tumor necrosis factor-beta (TNF-β), is a potent lymphoid factor that exerts cytotoxic effects on a wide range of tumor cells and certain other target cells. LT-α possesses a signal peptide sequence and is a secreted protein, however, LT-α is also present on the surface of activated T, B and LAK cells as a complex with LT-β. Bioactive LT-α exists as a homotrimer.
