Anti-LPLUNC3 antibodies enable researchers to detect and measure the LPLUNC3 antigen in biological samples. This target is a reported synonym of the BPIFB3 gene, which encodes BPI fold containing family B member 3. This protein is known to function in innate immune responses, among other biological roles. The human version of LPLUNC3 has a canonical amino acid length of 472 residues and a protein mass of 49.9 kilodaltons. It is reported to be localized in the cytoplasm and is secreted of cells. LPLUNC3 is a member of the BPI/LBP protein family.
