Rat Vitronectin, Active Protein, Cat#RPU60292
SDS-PAGE
Vitronectin (VTN ) is a glycoprotein of the hemopexin family which is abundantly found in serum, the extracellular matrix and bone. It is a secreted protein and exists in either a single chain form or a clipped, two chain form held together by a disulfide bond. VTN can binds to integrin alpha-V beta-3 and thus promotes cell adhesion and spreading. It also binds to plasminogen activator inhibitor-1 (PAI-1) and serves to regulate proteolysis initiated by plasminogen activation. Besides, Insulin Like Growth Factor Binding Protein 5 (IGFBP5) has been identified as an interactor of VTN, thus a binding ELISA assay was conducted to detect the interaction of recombinant Rat VTN and recombinant Rat IGFBP5. Briefly, VTN were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100ul were then transferred to IGFBP5-coated microtiter wells and incubated for 2h at 37°C. Wells were washed with PBST and incubated for 1h with anti-VTN pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution , wells were incubated 15-25 minutes at 37°C. Finally, add 50uL stop solution to the wells and read at 450nm immediately. The binding activity of VTN and IGFBP5 was shown, and this effect was in a dose dependent manner.

Let customers speak for us

from 218 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
