Description générale
Integrin alphaVbeta3 was purified from human placenta by affinity chromatography using immobilized monoclonal antibodies to alphaVbeta3 integrin. A tissue detergent extract, which was applied to the column was prepared as previously described [Belkin, 1990].
Two main protein bands corresponding to alphaV (145 kDa) and beta3 (92 kDa) subunits are seen in silver stained polyacrylamide gels under non-reducing conditions. Minor protein band (170 kDa) corresponds to beta3 subunit disulfide dimer.

Remarque sur l'analyse
7.5% SDS-PAGE by the method of Laemmli gives two major protein bands, corresponding to alpha V subunit (145 kDa) and beta 3 subunit (92 kDa) when visualized by silver stain (2-2.5 mg protein / lane nonreduced).A minor protein band (170 kDa) corresponds to the beta 3 dimer, similar to an occurrence of the beta 1 dimer upon purification of beta 1 integrins [Belkin et al., 1996].In some cases a beta 3 trimer is visible at 260 kDa.After reduction, with protein quantities of 1.5 - 4μg protein / lane, three major protein bands are apparent, corresponding to beta 3 integrin subunit (110 kDa), heavy alpha V chain (125 kDa) and light alpha V chain (25 kDa).A minor band at 200 kDa region is presumed to be the reduced beta 3 dimer, consistent with previous publications describing a 230 kDa beta 1 reduced dimer for beta 1 integrin purifications described previously.[Belkin et al.,1996].Faint bands at 80 kDa and 55 kDa correspond to minor degradation products of beta 3.CONTAMINANTS: Two faint bands identified at 210 and 220 kDa, which may correspond to the alpha V dimer.
Specific Activity: Functional activity confirmed by interaction of integrin alphaV/beta3 with vitronectin, von Willebrand Factor, fibrinogen, and fibronectin in RGD-dependent ELISA testing.

The up-regulation of various matrix metalloproteinases (MMP), certain cell receptors such as integrins and CD44, and the SIBLING family of integrin-binding glycophosphoproteins have been reported separately and in various combinations for many types of tumors. The mechanisms by which these

Integrins of the beta 1 family were isolated from human smooth muscle. SDS-PAGE analysis and subsequent immunoblotting demonstrated that integrin samples contain a protein immunologically related to beta 1 integrin subunit with the previously undescribed apparent molecular mass 205 kD.
