Anti-PLT1 antibodies enable researchers to detect and measure the PLT1 antigen in biological samples. This target is a reported synonym of the HLA-DPA1 gene, which encodes major histocompatibility complex, class II, DP alpha 1. This protein is known to function in adaptive immune responses, among other biological roles. The human version of PLT1 has a canonical amino acid length of 260 residues and a protein mass of 29.4 kilodaltons. It is reported to be localized in the ER, Golgi, lysosomes, and cell membrane of cells and notably expressed in many tissues, such as the lymph node and rectum. Other names for this target antigen include DP(W3), DP(W4), and DPA1. Western Blot is a widely used application for the PLT1 antibodies listed below. In addition, ELISA is also a common application.
