Monoclonal Mouse Affinity Purified E IC FC
Human Integrin beta 7 (also Integrin beta P and M290 IEL Ag) is a 120kD member of the integrin beta chain family of molecules. It is a type I transmembrane glycoprotein that contains a 704aa extracellular domain (ECD) (aa20-723) and a 52aa cytoplasmic tail. The ECD contains one von Willebrand factor A domain (aa150-389) and four cysteine-rich EGF-like repeats. One splice variant exists that shows a deletion of aa501-648. Integrin beta 7 forms a nondisulfide linked heterodimer with alpha 4 and alpha E integrins. Alpha 4 beta7 binds fibronectin, VCAM-1 and MADCAM1, while alpha E beta7 binds E-cadherin. The ECD of human beta 7 is 87% aa identical to the ECD of mouse beta 7.
Catalog #I7661-45C
ApplicationsSuitable for use in Flow Cytometry, Direct ELISA and Immunocytochemistry. Other applications not tested.
Recommended DilutionsFlow Cytometry: 0.2mg/ml using human peripheral blood lymphocytes. 10ul of the diluted solution labels 1-2.5x10e5 cells in a total reaction volume 200ul.
Direct ELISA: 0.5-1.0ug/ml. The detection limit for recombinant human Integrin beta 7 is ~1ng/well.
Immunocytochemistry: 10ug/ml to detect human Integrin beta 7 in huamn peripheral blood lymphocytes. Cells were fixed with PBS containing 4% paraformaldehyde for 20 minutes at RT and blocked with PBS containing 10% normal donkey serum, 0.1% Triton X-100, 1% BSA for 45 minutes at RT. After blocking, cells were incubated with diluted I7661-45C overnight at 4° C followed by fluorochrome-coupled anti-mouse IgG at RT in the dark for one hour. Between each step, cells were washed with PBS containing 0.1% BSA.
Optimal dilutions to be determined by the researcher.
