Western blot analysis of VEGFA polyclonal antibody (Cat # PAB4878) (arrow). 293 cell lysate (2 ug/lane) either nontransfected (Lane 1) or transiently transfected with the VEGF1 gene (Lane 2) (Origene Technologies). Molecular weight of monomeric VEGF1 is 27042 Da; higher observed molecular weight band is consistent with common form of disulfide linked homodimer.
Formalin-fixed and paraffin-embedded human breast carcinoma reacted with VEGFA polyclonal antibody (Cat # PAB4878) , which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry ; clinical relevance has not been evaluated.
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. [provided by RefSeq
