Anti-PLAC6 antibodies enable researchers to detect and measure the PLAC6 antigen in biological samples. This target is a reported synonym of the XAGE3 gene, which encodes X antigen family member 3. The human version of PLAC6 has a canonical amino acid length of 111 residues and a protein mass of 12.3 kilodaltons. It is reported to be notably expressed in the placenta. PLAC6 is a member of the GAGE protein family.
