Lysate Details for VEGF
HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.This product is manufactured by and sold under license from OriGene Technologies and its use is limited solely for research purposes.
Alternate Names for VEGF Overexpression Lysate (Native)

- VPFvascular endothelial growth factor
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]. Transcript Variant: This variant (6) lacks two alternate in-frame exons, compared to variant 1. The resulting protein (isoform f, also referred to as VEGF121) is shorter than isoform a. This variant initiates translation from four non-AUG (CUG) sites, and also from a downstream, in-frame AUG. Publication Note: This RefSeq record includes a subset of the publications that are available for this gene. Please see the Entrez Gene record to access additional publications.

FAQs for VEGF Lysate (NBL1-17712). (Showing 1 - 1 of 1 FAQ).
Why is the molecular weight of VEGF different from the similar antibody, for some companies the the molecular weight is 40KD)?
- I can't comment on another company's antibody because I don't have any information about their products. I can tell you that VEGF is expressed in a variety of isoforms and is subject to various post-translational modifications that influence its apparent molecular weight in an SDS-PAGE gel compared to the theoretical molecular weight.
