Anti-DLL1 antibodies are used in the immunodetection of the protein delta like canonical Notch ligand 1. In humans, the canonical protein has a reported length of 723 amino acid residues and a mass of 78.1 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the heart and pancreas, with lower expression in the brain and muscle and almost no expression in the placenta, lung, liver and kidney. DLL1 is known to be involved with the differentiation of certain cell types. Post-translational modifications have been described, including glycosylation, ubiquitination and phosphorylation. Synonyms for this target antigen include DL1, Delta, NEDBAS, delta-like protein 1, H-Delta-1, and DELTA1. DLL1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 140 citations in the literature describe the use of DLL1 antibodies in research. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
