Protein Molecular Weight

Know your sample

Getting an accurate reading of protein molecular weight helps in determining the identity of a particular protein, it can also be helpful in detecting modifications, ligand binding or complex formation. ProbeDrum helps you accomplish this by combining automated titration, sensitive light scattering measurements and a powerful analysis software.

How it Works

Based on Rayleigh theory, light scattering can be used to determine molecular weight of polymers, such as proteins, by measuring how the refractive index of a sample changes with concentration. Measuring the scattering signal at multiple protein concentrations and combining Low Angle- and Right Angle scattering yields accurate and sensitive results.
