| Short Description: |
This PF4 Sandwich ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human cell culture supernatant, serum and plasma (EDTA, citrate, heparin). |
| 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: |
Colormetric |
| Gene Symbol: |
PF4 |
| Gene ID: |
5196 |
| Uniprot ID: |
PLF4_HUMAN |
| Specificity: |
This kit recognizes Human PF4 in samples. No significant cross-reactivity or interference between Human PF4 and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Function | Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form. |
