RARRES1 (Retinoic Acid Receptor Responder 1; also Tig1) is a member of the protease inhibitor I47 family of proteins. It is expressed in epithelium, including keratinocytes, plus prostate and breast epithelium. It is considered to be a tumor-suppressor molecule, presumably acting as an inhibitor of carboxypeptidase A. Mouse RARRES1 is 349 amino acids (aa) in length. Based on human, it is a type II transmembrane (TM) protein with a TM segment at, or near, aa75-95. One potential 350aa splice variant exists that shows an almost complete aa divergence after Pro105.
Catalog #R1691-97
ApplicationsSuitable for use in Direct ELISA, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended DilutionDirect ELISA: 0.5-1ug/ml; Detection limit is ~0.3ng/well.
Western Blot: 1ug/ml
Immunohistochemistry (Fluorescence): 10ug/ml; Detects RARRES1 in cryosections of mouse liver. Tissue was fixed overnight in 4% PFA + 14% picric acid in PBS at 4°C. Sections were blocked with 10% donkey serum and 0.1% Triton X-100 in PBS, 1% BSA for 45 minutes at RT. After blocking, sections were incubated with R1691-97 for 3 hours at RT, followed by donkey anti-goat IgG (NL557) for 1 hour at RT. Between each step, cells were washed with PBS, 0.1% BSA.
Optimal dilutions to be determined by the researcher.
