Pre-Stained Protein Ladder

I have been using pre-stained standards in protein gel electrophoresis, and it's proven to be a valuable tool for quick and easy evaluation of electrophoresis and western transfer efficiency. With 10 proteins ranging from 4–250 kDa, including contrasting blue and red colors, I find it very useful and convenient to cut the membranes for western blot. The ready-to-use format allows for direct loading onto gels, therefore I highly recommend it for its efficiency and convenience.
