Anti-RASGEF1B antibodies are used in the immunodetection of the protein RasGEF domain family member 1B. In humans, the canonical protein has a reported length of 473 amino acid residues and a mass of 55.4 kDa. Its subcellular localization is in the endosome. Up to 3 different isoforms have been reported for this protein. Synonyms for this target antigen include ras-GEF domain-containing family member 1B and GPI gamma-4. RASGEF1B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. ELISA is a widely used application for the RASGEF1B antibodies listed below. In addition, Western Blot is also a common application.
