Recombinant Human ERBB3(Ser 20 - Thr 643) fused with His tag at C-terminal was expressed in HEK293.
Predicted N Terminal:
Lyophilized from 0.22µm filtered solution in PBS (pH 7.4) with Trehalose as protectant.
The protein has a calculated MW of 71.5 kDa. The protein migrates as 100-110 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.
Ser 20 - Thr 643
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower. Please avoid repeated freeze-thaw cycles.No activity loss is observed after storage at:4-8 centigrade for 12 months in lyophilized state;-70 centigrade for 3 months under sterile conditions after reconstitution.
Reconstitute at 100 μg/mL in sterile deionized water. For best performance, we strongly recommend you to follow the reconstitution protocol provided in the COA.
