Integrin alpha subunits purified from adult chicken brain tissue, denatured in 6M guanidine isothiocyanate, and depleted of beta1 subunit
Integrins are a family of heterodimeric membrane glycoproteins consisting on non-covalently associated alpha and beta subunits. In general, integrins function as receptors for extracellular matrix proteins. Applications: Suitable for use in Western Blot, Immunoprecipitation, Immunocytochemistry and Immunohistochemistry. Other applications have not been tested. Recommended Dilutions: Western Blot: Recognizes a 130kD band in chicken brain tissue and a 140kD band in transfected NIH3T3 cells (the difference in molecular weight is likely due to differential glycosylation). Immunoprecipitation: Precipitates the monomeric alpha6 subunit after the dimeric receptor has been denatured, but does not precipitate the native receptor. Immunocytochemistry: Methanol-fixed cultured cells (15 minute fixation). Immunohistochemistry (Methanol-fixed cryosections): 35ug/ml An overnight methanol fix is suggested. Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20C. Aliquots are stable at -20C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
