Anti-AGM4 antibodies are protein reagents that detect specific antigens. The AGM4 antigen is another term for the human protein B cell linker, encoded by the BLNK gene. The protein is known to function as a central linker protein, downstream of the B-cell receptor (BCR), bridging the SYK kinase to a multitude of signaling pathways and regulating biological outcomes of B-cell function and development. Canonically, it has an amino acid length of 456 residues and a mass of 50.5 kilodaltons. Its subcellular localization is in the cell membrane and cytoplasm and it is reported to be expressed in B-cell lineage and fibroblast cell lines. Other alias names for AGM4 include BASH. Western Blot is the most common application for the AGM4 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
