chicken integrin.1

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 1% bovine serum albumin with 15 mM sodium azide.


The antibody recognizes an epitope on the extracellular side of the avian integrin complex, and inhibits adhesion of embryo and tendon fibroblasts as well as skeletal myoblasts to both laminin and fibronectin. Under reducing and denaturing conditions using extracts of chicken embryo muscle cells, the antibody precipitates the β1 class integrin heterodimer as a broad band of ~140 kDa. In the absence of reducing agents, the integrin β1 subunit appears as bands at 100 kDa (immature form), 100 kDa (mature form), and 140 kDa (noncovalently associated α-subunits). The antibody may also be used for bioactivity studies in adhesion assays.
