Anti-ZPLD1 antibodies are used in the immunodetection of the protein zona pellucida like domain containing 1. In humans, the canonical protein has a reported length of 415 amino acid residues and a mass of 45.5 kDa. Its subcellular localization is in the extracellular matrix and is secreted. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the placenta, kidney, lung, pancreas and at very low level in other tissues. Post-translational modifications have been described, including protein cleavage and glycosylation. Synonyms for this target antigen include ZP domain-containing protein 1, cupulin, and zona pellucida-like domain-containing protein 1. ZPLD1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some ZPLD1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
