Description
VEGFA Antibody is a Rabbit Polyclonal antibody against VEGFA. This gene is a member of the PDGF/VEGF growth factor family and encodes a protein that is often found as a disulfide linked homodimer. This protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, and inhibiting apoptosis. Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy. Alternatively spliced transcript variants, encoding either freely secreted or cell-associated isoforms, have been characterized. There is also evidence for the use of non-AUG (CUG) translation initiation sites upstream of, and in-frame with the first AUG, leading to additional isoforms.

Descripción
VEGFA is a key member of the vascular endothelial growth factor (VEGF) family and plays a crucial role in angiogenesis, vascular permeability, and endothelial cell proliferation VEGFA binds primarily to its receptors VEGFR-1 and VEGFR-2, triggering signaling pathways like PI3K/AKT and ERK/MAPK to promote blood vessel formation during embryonic development, wound healing, and tissue repair Dysregulated VEGFA expression is associated with pathological angiogenesis observed in cancer, diabetic retinopathy, and age-related macular degeneration (AMD) VEGFA also increases vascular permeability by altering endothelial junctions, contributing to fluid leakage in conditions such as inflammation and tumors Targeted therapies, such as bevacizumab and other anti-VEGF agents, inhibit VEGFA activity to suppress angiogenesis and tumor growth in various cancers and ocular diseases

VEGFA antibody
VEGFA, also named as VEGF or VPF, belongs to the PDGF/VEGF growth factor family. It is a growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. VEGFA induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. It binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. Defects in VEGFA are a cause of susceptibility to microvascular complications of diabetes type 1(MVCD1). VEGFA has 13 isoforms with MW 16kd to 45kd. Some isoforms has homodimer form, such as VEGFA189(38kd), VEFGA110(34kd). VEGFA is a 34kd to 42kd, dimeric, disulfide-bound glycoprotein. VEGF-A exists in at least seven homodimeric isoforms. The monomers consist of 121, 145, 148, 165, 183, 189, or 206 amino acids(PMID:15602010).
