Molecular weight determination
Rather than using SDS-PAGE to check the protein size, we provide you to determine the molecular size by mass with error range under ±1Da (high solution).
Usually, we estimate the protein size by SDS-PAGE method. However, if you want to know the more precise molecular weight, mass will be a great choice for you. With the high resolution, the error range is lower than ±1Da. This service is suitable for confirming the synthesis peptide or the expression protein size is fitting your expextation.
