Anti-LCF antibodies enable researchers to detect and measure the LCF antigen in biological samples. This target is a reported synonym of the IL16 gene, which encodes interleukin 16. This protein is known to function in cytokine-mediated signaling pathways and immune response pathways, among other biological roles. The human version of LCF has a canonical amino acid length of 1332 residues and a protein mass of 141.8 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus, cytoplasm, and is secreted of cells and notably expressed in the rectum, lymph node, colon, bone marrow, and appendix. Other names for this target antigen include NIL16 and PRIL16. Western Blot is a widely used application for the LCF antibodies listed below. In addition, ELISA is also a common application.
