Short Description: This human CTLA4 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: CTLA4
Gene ID: 1493
Uniprot ID: CTLA4_HUMAN
Specificity: This kit recognizes Human CTLA4 in samples. No significant cross-reactivity or interference between Human CTLA4 and analogues was observed.
Sample Type: Serum, plasma and other biological fluids
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.
