CTLA-4 Protein, Cynomolgus, Recombinant (hFc)

Cytotoxic Tlymphocyte 4(CTLA-4,CD152), is a type I transmembrane T cell inhibitory molecule that is a member of the Ig superfamily.CD28 and CTLA-4, together with their ligands, B7-1 and B7-2, constitute one of the dominant costimulatory pathways that regulate T and B cell responses. CD28 and CTLA-4 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T Cells and may play an important role in their functions. Tcell activation through the Tcell receptor and CD28 leads to increased expression of CTLA4.

Amino Acid	Ala37-Ser160
Construction	Recombinant Cynomolgus Cytotoxic T-lymphocyte Associated Protein 4 is produced by our Mammalian expression system and the target gene encoding Ala37-Ser160 is expressed with a human IgG1 Fc tag at the C-terminus.
Protein Purity	Greater than 95% as determined by reducing SDS-PAGE. (QC verified)
Molecular Weight	45-60 KDa, reducing conditions

Endotoxin	Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Formulation	Lyophilized from a 0.2 μm filtered solution of 50 mM Tris-HCl, 100 mM Glycine, pH 7.5.
Reconstitution	Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Stability & Storage	Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
Shipping	The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
