The OmniKine Human VEGF ELISA can be used to reconize both recombinant and naturally produced (by human) Human VEGF proteins. The following antigens were tested at 50 ng/ml and showed 100% cross reactivity. • Human: VEGF121 • Rat: VEGF • Murine: VEGF. Those tested at 50 ng/ml and did not showed significant interference or cross reactivity. • Human: EGF, EG-VEGF, PDGF-BB, PDGF-CC, RANTES, SCF, VEGF-B, VEGF-C, FGF-16, GM-CSF, PDGF-AA, PDGF-AB, • Rat: EGF, SCF • Murine: EGF, GM-CSF, PDGF-AA, PDGF-BB, SCF.
