| Form | Lyophilized To keep the original salt concentration, we recommend reconstituting to the original concentration prior to lyophilization (see Concentration) in ddH2O. If a lower concentration is required, dilute in 20 mM Tris, 150 mM NaCl, pH 8.0. If a higher concentration is required, the product can be reconstituted directly in 20 mM Tris, 150 mM NaCl, pH 8.0, though please note that this will change the overall salt concentration. The stock concentration should be between 0.1-1.0 mg/ml. Do not vortex. |

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).
