Anti-PLAC1L antibodies enable researchers to detect and measure the PLAC1L antigen in biological samples. This target is a reported synonym of the OOSP2 gene, which encodes oocyte secreted protein 2. This protein is known to be involved in oocyte maturation. The human version of PLAC1L has a canonical amino acid length of 158 residues and a protein mass of 18 kilodaltons. It is reported to be a secreted protein that is notably expressed in the testis. PLAC1L is a member of the PLAC1 protein family.
