This product consists of 10 highly purified and prestained proteins ranging in molecular weight from 8 kDa to 180 kDa (8,17,25,33,43,55,72,100,130,180kDa), among them, 72 kDa is orange band, 8 kDa is green band. The labeled apparent molecular weight was calibrated by the molecular weight Marker of standard non-prestained proteins. Using this product, the state of protein electrophoresis and the effect of membrane transfer can be dynamically observed. After SDS-PAGE electrophoresis, the color bands were transferred to PVDF membrane and NC membrane. This product is conveniently packaged and is a ready-to-use product, do not heat, dilute or add reducing agents!
After the prestained protein is combined with the dye, the molecular weight will change in the gel of different concentrations. There are signs in the instructions, this product is only for reference when judging the molecular weight of the target protein.
