Host: HEK293
Applications: ELISA/WB
Note: STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
Short Description: Recombinant-Human CTLA4 (CD152)-protein was developed from hek293. For use in research applications.
Conjugation: Biotin
Formulation: Lyophilised from 0.2 Mu m filtered PBS pH 7.4.
Dilution Range: Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers.
Storage Instruction: Can be stored in working aliquots at 2°C-8°C C for one month, or at-20°C C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles. NA
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). NA
Gene Symbol: CTLA4
Gene ID: 1493
Uniprot ID: CTLA4_HUMAN
Immunogen Region: ECD
Immunogen: DNA sequence encoding extracellular domain of Human CTLA4 to a C-terminal polyHis tag was expressed in HEK cells. NA
Tissue Specificity Widely expressed with highest levels in lymphoid tissues. Detected in activated T-cells where expression levels are 30- to 50-fold less than CD28, the stimulatory coreceptor, on the cell surface following activation.
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.
