Beschreibung

Allgemeine Beschreibung

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.

Anwendung

Electrophoresis and Immunoblotting control. Also useful for in vitro binding

experiments with metalloproteinase MMP-2 .

Physikalische Form

Purified protein in 20 mM Tris-HCI, pH 7.5, 150 mM NaCI, 2 mM MgCI2, 0.2% Triton X-100. No preservatives.

Lagerung und Haltbarkeit

Maintain at -70°C in undiluted aliquots. Avoid repeated freeze/ thaw cycles.

Hinweis zur 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.
