Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-VCAM-1 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-VCAM-1 polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the VCAM-1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of VCAM-1 can be calculated!!Background/Introduction: Vascular cell adhesion protein 1 (VCAM-1), also known as cluster of differentiation 106 (CD106) is a protein that in humans is encoded by the VCAM1 gene. This gene contains 9 exons spanning about 25 kb, and It is expressed on both large and small blood vessels only after the endothelial cells are stimulated by cytokines. The VCAM-1 is a cell surface sialoglycoprotein, a type I membrane protein that is a member of the Ig superfamily. It mediates the adhesion of lymphocytes, monocytes, eosinophils, and basophils to vascular endothelium. It also functions in leukocyte-endothelial cell signal transduction, and it may play a role in the development of atherosclerosis and rheumatoid arthritis.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a member of the platelet-derived growth factor/vascular endothelial growth factor (PDGF/VEGF) family and is active in angiogenesis, lymphangiogenesis, and endothelial cell growth. This secreted protein undergoes a complex proteolytic maturation, generating multiple processed forms which bind and activate VEGFR-2 and VEGFR-3 receptors. This protein is structurally and functionally similar to vascular endothelial growth factor C. Read-through transcription has been observed between this locus and the upstream PIR (GeneID 8544) locus. [provided by RefSeq, Feb 2011]
Uniprot Description
VEGFD: Growth factor active in angiogenesis, lymphangiogenesis and endothelial cell growth, stimulating their proliferation and migration and also has effects on the permeability of blood vessels. May function in the formation of the venous and lymphatic vascular systems during embryogenesis, and also in the maintenance of differentiated lymphatic endothelium in adults. Binds and activates VEGFR-2 (KDR/FLK1) and VEGFR-3 (FLT4) receptors. Belongs to the PDGF/VEGF growth factor family.

Product Notes
The Human VEGF-D figf (Catalog #AAA494833) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA494833 ELISA Kit recognizes Human VEGF-D. It is sometimes possible for the material contained within the vial of "VEGF-D, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
