Human VEGF / VEGFA / VEGF165 Protein (His & AVI Tag), Biotinylated
A DNA sequence encoding the human VEGF165 (Ala 27-Arg 191) was expressed with a c-terminal polyhistidine tagged AVI tag at the C-terminus. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed.
> 95 % as determined by SDS-PAGE.
Lyophilized from sterile PBS, pH 7.4.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
