| Short Description : | This human VWF kit is a highly sensitive in-vitro chemiluminescent immunoassay for the measurement of trace amounts of analytes in serum, plasma and other biological fluids. |
| Storage Instruction: | If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual. |
| Assay Time: | 3.5h |
| Detection: | Chemiluminescence |
| Gene Symbol: | VWF |
| Gene ID: | 7450 |
| Uniprot ID: | VWF_HUMAN |
| Specificity: | This kit recognizes Human VWF in samples. No significant cross-reactivity or interference between Human VWF and analogues was observed. |
| Sample Type: | Serum, plasma and other biological fluids |
| Tissue Specificity | Plasma. |
| Post Translational Modifications | All cysteine residues are involved in intrachain or interchain disulfide bonds. N- and O-glycosylated. |
| Function | Important in the maintenance of hemostasis, it promotes adhesion of platelets to the sites of vascular injury by forming a molecular bridge between sub-endothelial collagen matrix and platelet-surface receptor complex GPIb-IX-V. Also acts as a chaperone for coagulation factor VIII, delivering it to the site of injury, stabilizing its heterodimeric structure and protecting it from premature clearance from plasma. |
