Invitrogen™ Rat VEGFR1 ELISA Kit

FLT1 (VEGFR1) is a receptor tyrosine kinase which plays a critical role in angiogenesis. Active angiogenesis has been found to play important role in many pathological and physiological processes, such as tumor progression, diabetic retinopathy, rheumatoid arthritis and wound healing. May play an essential role as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells. Can promote endothelial cell proliferation, survival and angiogenesis in adulthood. Its function in promoting cell proliferation seems to be cell-type specific. Promotes PGF-mediated proliferation of endothelial cells, proliferation of some types of cancer cells, but does not promote proliferation of normal fibroblasts (in vitro). Has very high affinity for VEGFA and relatively low protein kinase activity; may function as a negative regulator of VEGFA signaling by limiting the amount of free VEGFA and preventing its binding to KDR.
