Product Properties Synonyms αVβ3; alphaV; beta3; Integrin alpha V β 3 Source Mouse Integrin alpha V beta 3 (ITGAV&ITGB3) Heterodimer Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Phe31-Val988(ITGAV) acidic tail & Glu26-Asp717(ITGB3) basic tail.[Accession | P43406(ITGAV)&O54890(ITGB3)] Molecular Weight The protein has a predicted MW of 131.48 kDa(ITGAV)&101.58 kDa(ITGB3). Due to enzyme lysis and glycosylation, the protein migrates to 110-135 kDa and 50-60 kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity SPR Data: Mouse ITGAV&ITGB3, hFc Tag captured on CM5 Chip via Protein A can bind Human Vitronectin, His Tag with an affinity constant of 3.37 nM as determined in SPR assay . Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 -6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Note 1.Please operate with lab coats and disposable gloves,for your safety. 2.This product is for research use only.
