The LY57 ELISA kits listed below utilize specific antibodies for the plate-based assay of LY57 in various samples. LY57 is another term for the BLNK gene, which encodes the protein, B cell linker in humans. It has been reported that LY57 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.
