The HGF single chain can be processed into the active form of disulfide-linked heterodimer of α and β chain.The protein has a predicted MW of 79.6 kDa (after cleavage of the signal peptide). Due to glycosylation, the protein migrates to 60-65 kDa corresponding to α chain and β chain based on Bis-Tris PAGE result.

运输及存储
产物表面
Lyophilized
运输前提
Shipped at ambient temperature.
制剂
Lyophilized from 0.22μm filtered solution in 20mM Tris, 150mM NaCl, 300mM Arginine (pH 7.5). Normally 8% trehalose is added as protectant before lyophilization.
复溶
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/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.
