Cat.No. : ITGA5&ITGB1-358H
Product Overview : Recombinant Human ITGA5 & ITGB1 Heterodimer Protein, His-tagged is expressed from human 293 cells (HEK293). It contains AA Phe 42 - Tyr 995 (ITGA5) & Gln 21 - Asp 728 (ITGB1) (Accession # P08648-1 (ITGA5) & P05556-1 (ITGB1)). Predicted N-terminus: Phe 42 (ITGA5) & Gln 21 (ITGB1). Human ITGA5 & ITGB1 Heterodimer Protein, produced by co-expression of ITGA5 and ITGB1, has a calculated MW of 104.1 kDa (ITGA5) and 83.7 kDa (ITGB1). Subunit ITGA5 is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB1 contains no tag but a basic tail at the C-terminus. The reducing (R) protein migrates as 117-150 kDa (ITGA5) and 100-116 kDa (ITGB1) respectively due to glycosylation.
Source : HEK293
Species : Human
Tag : His
Form : Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
Bio-activity : Immobilized Human Fibronectin at 2 μg/mL (100 μL/well) can bind Recombinant Human ITGA5 & ITGB1 Heterodimer Protein, His-tagged with a linear range of 0.2-2 ng/mL (QC tested).
Molecular Mass : 104.1 kDa (ITGA5) & 83.7 kDa (ITGB1)
Protein length : Phe 42 - Tyr 995 (ITGA5) & Gln 21 - Asp 728 (ITGB1)
Endotoxin : Less than 1.0 EU per μg by the LAL method.
Purity : >95% as determined by SDS-PAGE.
Notes : Please avoid repeated freeze-thaw cycles.
Stability : No activity loss is observed after storage at:
4-8 centigrade for 12 months in lyophilized state;
-70 centigrade for 3 months under sterile conditions after reconstitution.
Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
