Active Recombinant Human Vegfa protein(Met1-Asp147)

• Cat.No.: Vegfa-2104H
• Product Overview: Recombinant Human VEGF 121 isoform b (P15692-9) (Met1-Asp147,with last 6 amino acids switch from CDKPRR to SLTRKD ) was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: Non
• Protein length: Met1-Asp147
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1. Measured by its binding ability in a functional ELISA. Immobilized human VEGF121b at 10μg/mL (100μL/well) can bind human VEGFR2-Fc, the EC50 of human VEGFR2-Fc is 0.06-0.1 μg/mL. 2. Measured in a cell prolifeRation assay using human umbilical vein endothelial cells (HUVEC). The ED50 for this effect is typically 1-5ng/mL.
• Molecular Mass: The recombinant human VEGF consists of 121 amino acids and has a predicted molecular mass of 14 kDa. The apparent molecular mass of the human VEGF121b is approximately 20 and 16 kDa in SDS-PAGE under reducing conditions due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
