Anti-CRELD1 antibodies are used in the immunodetection of the protein cysteine rich with EGF like domains 1. In humans, the canonical protein has a reported length of 420 amino acid residues and a mass of 45.4 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in fetal lung, liver, kidney, adult heart, brain and skeletal muscle. It is a member of the CRELD protein family. Post-translational modifications have been described, including glycosylation. The CRELD1 gene has been associated with the disease, Atrioventricular septal defect. Synonyms for this target antigen include protein disulfide isomerase CRELD1. CRELD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CRELD1 antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. Western Blot and Immunohistochemistry are also common applications.
