Recombinant Human BACE-1 Protein is expressed from HEK293 with hFc tag at the C-terminal.It contains Thr22-Thr457, which will be further processed into Thr22-Thr457(pro-form) & Glu46-Thr457(mature-form).
The protein has a predicted MW of 75.2 kDa (pro-form) and 72.6 kDa (mature-form). Due to glycosylation, the protein migrates to 85-100 kDa based on Tris-Bis PAGE result.

Shipped at ambient temperature.
制剂
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
复溶
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
存储和不变性
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
