| Short Description: |
This human CR1 kit is a highly sensitive in-vitro chemiluminescent immunoassay for the measurement of trace amounts of analytes. |
| 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: |
CR1 |
| Gene ID: |
1378 |
| Uniprot ID: |
CR1_HUMAN |
| Specificity: |
This kit recognizes Human CR1 in samples. No significant cross-reactivity or interference between Human CR1 and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Tissue Specificity | Present on erythrocytes, a subset of T cells, mature B cells, follicular dendritic cells, monocytes and granulocytes. |
| Function | Membrane immune adherence receptor that plays a critical role in the capture and clearance of complement-opsonized pathogens by erythrocytes and monocytes/macrophages. Mediates the binding by these cells of particles and immune complexes that have activated complement to eliminate them from the circulation. Acts also in the inhibition of spontaneous complement activation by impairing the formation and function of the alternative and classical pathway C3/C5 convertases, and by serving as a cofactor for the cleavage by factor I of C3b to iC3b, C3c and C3d,g, and of C4b to C4c and C4d. Also plays a role in immune regulation by contributing, upon ligand binding, to the generation of regulatory T cells from activated helper T cells. (Microbial infection) Acts as a receptor for Epstein-Barr virus. |
