  • C, simulated gel image of the same fractions using the Experion Pro260 analysis kit and protein ladder. (bio-rad.com)
  • The peaks in the electropherogram correlate with the bands in the simulated gel image (inset), allowing close analysis of target protein purity and of any impurities in the fractions. (bio-rad.com)
  • occurs
  • For example, reduced peptides must be desalted quickly to remove reductant and initiate subsequent sulfhydryl-reaction procedures before oxidation back to disulfides occurs. (thermofisher.com)
