Anti-C19orf53 antibodies are used in the immunodetection of the protein chromosome 19 open reading frame 53. In humans, the canonical protein has a reported length of 99 amino acid residues and a mass of 10.6 kDa. It is notably widely expressed in many tissue types. A member of the UPF0390 protein family, C19orf53 is suspected to have a potential role in hypercalcemia of malignancy. Synonyms for this target antigen include LYDG10, leydig cell tumor 10 kDa protein homolog, and HSPC023. C19orf53 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These C19orf53 antibodies are widely used in ELISA experiments, among other applications.
