Optimal preservation of protein structure, post-translational modifications and functions.
产品特性
Recombinant human VEGF-A (transcript variant 2) protein expressed in E. coli.
Produced with end-sequenced ORF clone
Tested for bioactivity.
内毒素水平
Less than 0.1 EU/μg (<0.01 ng/μg) protein as determined by the LAL method.
Biological Activity Comment
The ED50 is 1-4 ng/ml, corresponding to a specific activity of 1-0.25 x 10^6 units/mg, determined by the dose dependent stimulation of HUVEC cells proliferation.
Recombinant human proteins can be used for: Native antigens for optimized antibody production Positive controls in ELISA and other antibody assays Protein-protein interaction In vitro biochemical assays and cell-based functional assays
