| Formulation: | Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. |
| Bio-Activity: | Measured by its binding ability in a functional ELISA. Immobilized Mouse CTLA-4/CD152 at 2μg/mL (100μL/well) can bind Mouse B7-2/CD86 with a linear range of 0.1-51.8 ng/mL. |
| Reconstitution: | Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
| Storage: | Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. |
Cytotoxic T-lymphocyte protein 4, also known as CTLA4 and CD152, is a single-pass type I membrane protein and a member of the immunoglobulin superfamily. It is the second member of the CD28 receptor family,and is similar to the T-cell co-stimulatory protein, CD28, both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal.Intracellular CTLA4 is also found in regulatory T cells, CD152 or cytotoxic T lymphocyte antigen-4 (CTLA-4) is an essential receptor involved in the negative regulation of T cell activation. Because of its profound inhibitory role, CD152 has been considered a sound susceptible candidate in autoimmunity and a persuasive target for cancer immunotherapy.
 | Recombinant Mouse CTLA-4/CD152 Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue. |
 | Immobilized Mouse CTLA-4/CD152 at 2μg/mL (100μL/well) can bind Mouse B7-2/CD86 with a linear range of 0.1-51.8 ng/mL. |
