Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
Reconstitution
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.
Bioactivity-ELISA 1
Immobilized Human TROP-2-His at 2μg/ml (100 μl/well) can bind Anti-Human TROP-2 mAb. The ED50 of Anti-Human TROP-2 mAb is 13.03 ng/ml.
