Cancer
Relevance
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.
Endotoxin
Less than 1.0 EU/μg as determined by LAL method.
Purity
Greater than 90% as determined by SDS-PAGE.
Activity
Yes
Bioactivity
Measured by its binding ability in a functional ELISA. Immobilized CD152 at 2 μg/ml can bind Anti-CD152 rabbit monoclonal antibody (CSB-RA213310A0HU), the EC50 of human CD152 protein is 27.14-34.82 ng/ml.
Form
Lyophilized powder
Buffer
Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Molecular Weight
42.5 kDa
Storage Conditions
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
