Detects human Integrin beta 7 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant mouse Integrin beta 7 is observed and less than 1% cross-reactivity with recombinant human (rh) Integrin beta 2, rhIntegrin beta 5, and rhIntegrin beta 6 is observed.

Background: Integrin beta 7
Human Integrin beta 7 (also Integrin beta P and M290 IEL Ag) is a 120 kDa member of the Integrin beta chain family of molecules. It is a type I transmembrane glycoprotein that contains a 704 amino acid (aa) extracellular domain (ECD) (aa 20-723) and a 52 aa cytoplasmic tail. The ECD contains one von Willebrand factor A domain (aa 150-389) and four cysteine-rich EGF-like repeats. One splice variant exists that shows a deletion of aa 501-648. Integrin beta 7 forms a nondisulfide linked heterodimer with alpha 4 and alpha E integrins. alpha 4 beta 7 binds fibronectin, VCAM-1, and MADCAM1, while alpha E beta 7 binds E-cadherin. The ECD of human beta 7 is 87% aa identical to the ECD of mouse beta 7.
