I would like to buy biologically active human VEGFA protein. Not sure where to get it? Appreciate if anyone can share links of supplier names for it. I found one below from abcam and I think it is not biologically functioning. Let me know if you agreed with this too. See the link below.

A number of companies sell recombinant human and mouse VEGF-A. Abcam human VEGFA is a good place to start. The link you shared is for a NON ACTIVE VEGFA protein.
This page (https://www.abcam.com/products?keywords=human+recombinant+VEGFA) gives you important information on abcam proteins like if it is biologically active or not and full lenght protein versus protein fragment.
The concentration you use in your experiment is also important (usually 50ng/mL or 100ng/mL gives me good results).
Good luck with your experiments.
