| Description | Human Integrin α5β1, Triton X-100 Formulation |
| Overview | Integrin a5/b1 purified from smooth muscle and placental tissue under nondenaturing conditions by affinity chromatography on fibronectin-sepharose (Belkin, 1990). Two main protein bands corresponding to a5 (145 kD) and beta1 (120 kD) subunits are seen in silver stained 7.5% polyacrylamide gels under nonreduced conditions. Minor protein band at the 210 kD corresponding to beta1 subunit disulfide dimmer, which is formed during electrophoresis and disappears after reduction. |

| Presentation | Purified protein in 20 mm Tris-HCl, pH 7.5, 150 mm NaCl, 2 mm MgCl2 containing 0.2% Triton X-100. No preservatives. Source material for the enclosed purified human proteins, Integrin alpha5beta1, has been tested for antibodies to HIV, HCV, and HbsAg and found to be negative by an approved test. |

| Applications | |
|---|---|
| Key Applications |
|
| Application Notes | Electrophoresis and Immunoblotting control. Due to the existance of reduction sensitive sites within the integrin subunits, it is recommended that gels be run under non-reducing conditions for best results. Under non-reducing conditions, the alpha5 subunit will migrate at 155 kDa while the beta1 subunit will migrate at 110 kDa. Function: Liposomes containing Integrin alpha5/beta1 adhere to surfaces coated with fibronectin in an RGD-dependent fashion. |
| Biological Information | |
|---|---|
| Purity | Nonreduced SDS-PAGE of 15 μg on 5-15% polyacrylamide slab gel and staining with Coomassie shows only two main bands at 110 kDa (beta1 subunit) and 155 kDa (alpha5 subunit). A weak band at 205 kDa is due to dimerization of the b1 subunit (Belkin et Al., 1996). CONTAMINANT(S): None identified. |
| Source | Human smooth muscle and placental tissue. |
| Entrez Gene Number |
|
| Entrez Gene Summary | The product of this gene belongs to the integrin alpha chain family. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes the integrin alpha 5 chain. Alpha chain 5 undergoes post-translational cleavage in the extracellular domain to yield disulfide-linked light and heavy chains that join with beta 1 to form a fibronectin receptor. In addition to adhesion, integrins are known to participate in cell-surface mediated signalling. |
