The BCA ELISA kits listed below are analytical tools for measuring concentrations of BCA in various samples. BCA is an alternative name for the human BLNK gene, which encodes the protein, B cell linker. It has been mentioned that BCA plays a role in B cell differentiation and inflammatory response pathways, among other functions. Structurally, the BLNK protein is 456 amino acid residues in length and 50.5 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cell membrane and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in B-cell lineage and fibroblast cell lines. This protein is known to be phosphorylated. Other names for this target antigen include AGM4, AGM4, and BASH.
