Endotoxin

Less than 1.0 EU/ug as determined by LAL method.

Purity

Greater than 91% as determined by SDS-PAGE.

Biological Activity

Measured by its binding ability in a functional ELISA. Immobilized CD152 at 2 μg/ml can bind Anti-CD152 rabbit monoclonal antibody, the EC50 of human CD152 protein is 27.14-34.82 ng/ml.

Storage

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

SDS-PAGE

Bioactivity-ELISA 1

Measured by its binding ability in a functional ELISA. Immobilized CD152 at 2 ug/ml can bind Anti-CD152 rabbit monoclonal antibody, the EC50 of human CD152 protein is 27.14-34.82 ng/ml
