| Short Description: |
This POSTN 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 6 months. Following first use any unused wells and reagents should be stored according to the components table in the manual. |
| Assay Time: |
1.5h |
| Detection: |
Colormetric |
| Gene Symbol: |
POSTN |
| Gene ID: |
10631 |
| Uniprot ID: |
POSTN_HUMAN |
| Specificity: |
This kit recognizes Human POSTN/OSF-2 in samples. No significant cross-reactivity or interference between Human POSTN/OSF-2 and analogues was observed. |
| Sample Type: |
Serum and plasma |
| Post Translational Modifications | Gamma-carboxylation is controversial. Gamma-carboxyglutamated.gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation.this may be required for calcium binding. According to a more recent report, does not contain vitamin K-dependent gamma-carboxyglutamate residues. |
| Function | Induces cell attachment and spreading and plays a role in cell adhesion. Enhances incorporation of BMP1 in the fibronectin matrix of connective tissues, and subsequent proteolytic activation of lysyl oxidase LOX. |
