| Short Description: |
This CPB2 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: |
CPB2 |
| Gene ID: |
1361 |
| Uniprot ID: |
CBPB2_HUMAN |
| Specificity: |
This kit recognizes Human TAFI in samples. No significant cross-reactivity or interference between Human TAFI and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Post Translational Modifications | N-glycosylated. N-glycan at Asn-108: Hex5HexNAc4. |
| Function | Cleaves C-terminal arginine or lysine residues from biologically active peptides such as kinins or anaphylatoxins in the circulation thereby regulating their activities. Down-regulates fibrinolysis by removing C-terminal lysine residues from fibrin that has already been partially degraded by plasmin. |
