Name : Human VEGF121 Protein
Product Source :
Recombinant Human VEGF121 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ala27-Arg147.[Accession | P15692-9]
Molecular Weight :
The protein has a predicted MW of 17 kDa. Due to glycosylation, the protein migrates to 18 kDa and 22-25 kDa under reduced (R) condition, 30 kDa and 32-40 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE
Formulation :
Lyophilized from 0.22μm filtered solution in PBS,250mM Arginine (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 and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human VEGF121 on Tris-Bis PAGE under reduced (R) condition and Non reducing (N) condition. The purity is greater than 95%. ELISA Data Immobilized Human VEGF121, His Tag at 2μg/ml (100ul/Well). Dose response curve for Biotinylated Human VEGFR1, His Tag with the EC50 of 42ng/ml determined by ELISA.
Background :
Vascular endothelial growth factor (VEGF or VEGF-A), also known as vascular permeability factor (VPF), is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. VEGF165 appears to be the most abundant and potent isoform, followed by VEGF121 and VEGF189.
Synonyms :
VEGF; VEGFA; MVCD1; VAS; VEGFMGC70609; VPF; RP1-261G23.1; MGC70609
