    NEB offers a selection of highly pure protein markers and ladders available in unstained, prestained or ColorPlus™ (prestained containing two colored bands for easy identification) formats. Sizes range from 2.3 to 250 kDa which is ideal for accurate molecular weight determination for a wide range of expressed proteins. NEB markers and ladders provide uniform band intensities, convenient band spacing and easy-to-identify reference bands.
