Anti-SRP68 antibodies are used in the immunodetection of the protein signal recognition particle 68. In humans, the canonical protein has a reported length of 627 amino acid residues and a mass of 70.7 kDa. Its subcellular localization is in the nucleus, ER, and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the SRP68 protein family, SRP68 is a known component of the signal recognition particle (SRP) complex, a ribonucleoprotein complex that mediates the cotranslational targeting of secretory and membrane proteins to the endoplasmic reticulum (ER). Synonyms for this target antigen include signal recognition particle 68 kDa protein, signal recognition particle 68kD, signal recognition particle 68kDa, and signal recognition particle subunit SRP68. SRP68 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SRP68 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
