These BTN ELISA kits are immunodetection tools for measuring the levels of BTN in biological samples. BTN is an alias of the human BTN1A1 gene, which encodes the protein, butyrophilin subfamily 1 member A1. The protein is believed to function in the secretion of milk-fat droplets. The BTN1A1 protein is described to be 526 amino acid residues in length and 59 kilodaltons in mass. Its subcellular localization is in the membrane and is secreted. This protein is known to be N-glycosylated. Other names for this target antigen include BT.
