Recombinant monoclonal antibody Fragment Fab to Human VEGF. Ranibizumab (trade name ranibizumab) is a monoclonal antibody fragment (Fab) derived from the same parent mouse antibody as bevacizumab (bevacizumab). It is much smaller than the parent molecule and has been affinity matured to provide stronger binding to VEGF-A. It is an anti-angiogenic that has been approved to treat the "wet" type of age-related macular degeneration (AMD, also ARMD), a common form of age-related vision loss.
Fab - G1 - kappa
Purified intact human VEGF
Suitable for use in IP, IF, FuncS, FC, Neut, ELISA, IHC and most other immunological methods.
Tested positive against native human antigen
Immunoglobulin G1, anti-(human vascular endothelial growth factor) Fab fragment
>95.0% as determined by analysis by SDS-PAGE.
Store at 4°C for up to 3 months. For longer term storage aliquot into small volumes and store at -20°C.
Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth.
