The protein has a predicted MW of 44.2 kDa. Due to glycosylation, the protein migrates to 40-50 kDa(LAP) / 13-15 kDa(Mature TGF Beta 1) kDa based on Tris-Bis PAGE result.
活性

运输及存储
产物表面
Lyophilized
运输前提
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.
