Endotoxin

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

Purity

Greater than 92% as determined by SDS-PAGE.

Biological Activity

①Measured by its binding ability in a functional ELISA. Immobilized CD40 at 2 μg/ml can bind CD40L, the EC50 is 3.112-3.858 ng/ml.②Human CD40 protein hFc tag captured on COOH chip can bind Human CD40L protein hFc and Flag tag with an affinity constant of 2.06 nM as detected by LSPR Assay.

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.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.
