Recombinant cynomolgus ERBB2 (Met1-Thr652) [similar to Macaca fascicularis ERBB2 (EHH58073.1)] was expressed with a polyhistidinetag atthe C-terminus.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
Measured by its binding ability in a functional ELISA. Immobilized Cynomolgus ERBB2-His at 10 μg/ml (100 μl/well) can bind Herceptin, The EC50 of Herceptin is 16.4-38.4 ng/ml.
The recombinant cynomolgus ERBB2 comprises 641 amino acids and has a calculated molecular mass of 70.8 KDa. The apparent molecular mass of it is approximately 80-105 KDa in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>90 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
