• How to Measure Molecular Weight of Protein
The ability to measure molecular weight of protein is a critical step in biochemical research, enabling scientists to understand the structure, function, and interactions of proteins with other molecules. Accurate measurement of protein molecular weight is essential for protein purification, functional studies, and drug development. Protein molecular weight is typically expressed in daltons (Da), equivalent to the mass of a hydrogen atom. Multiple methods exist to measure molecular weight of protein, ......

• How Does Mass Spectrometry Work for Proteins
Mass spectrometry is a powerful technique widely used in protein analysis to separate and detect molecules based on their mass-to-charge ratio (m/z). In this process, sample molecules are ionized, and the resulting ions are accelerated or deflected by electric or magnetic fields. This allows for the separation of ions according to differences in their mass and charge. The intensity and m/z ratios of the ions are then recorded by a detector, generating a mass spectrum that provides detailed information......
