Anti-RYSR antibodies enable researchers to detect and measure the RYSR antigen in biological samples. This target is a reported synonym of the BPIFB2 gene, which encodes BPI fold containing family B member 2. The human version of RYSR has a canonical amino acid length of 458 residues and a protein mass of 49.2 kilodaltons. It is reported to be a secreted protein that is notably expressed in the salivary gland. RYSR is a member of the BPI/LBP protein family. Indicated applications for RYSR antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
