Short Description: |
Recombinant-Human CTLA-4/CD152-C-His-Avi protein was developed from hek293 and has a target region of C-His-Avi. For use in research applications. |
Conjugation: |
Biotin |
Formulation: |
Lyophilised from 0.2 µm filtered PBS solution pH7.4. |
Dilution Range: |
Upon receipt centrifuge vial to ensure maximal product extraction, recommended: 20sec, 5K RPM |
Storage Instruction: |
The lyophilized protein is stable for at least 1 year from date of receipt at-20°C. |
Endotoxin: |
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). |
Gene Symbol: |
CTLA4 |
Gene ID: |
1493 |
Uniprot ID: |
CTLA4_HUMAN |
Immunogen Region: |
Lys36-Asp161 |
Immunogen: |
DNA sequence encoding Human CTLA-4/CD152 including a C-His-Avi tag was expressed in HEK293 Cells. The recombinant protein was then biotinylated site specific using the AVItag biotinylation technology. |
Post Translational Modifications | N-glycosylation is important for dimerization. Phosphorylation at Tyr-201 prevents binding to the AP-2 adapter complex, blocks endocytosis, and leads to retention of CTLA4 on the cell surface. |
Function | Inhibitory receptor acting as a major negative regulator of T-cell responses. The affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28. |
