Host: HEK293
Note: STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
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.
