DNA Molecular Weight Markers
New England Biolabs sells a wide range of double-stranded DNA molecular weight markers for electrophoresis. We offer conventional DNA markers as well as a wide range of DNA ladders, ranging from 10 bp up to 48.5 kb. We also offer markers suitable for use in Pulsed-field gel electrophoresis (PFGE) extending up to > 1000 kb. DNA ladders from NEB are available in a variety of formats, including different ready-to-load formats as well as standard formats without pre-mixed loading dye. All standard ladders are provided with a vial of purple loading dye for added convenience. With our popular Quick-Load Purple DNA Ladders, take advantage of crisp bands and improved visibility, as there's no UV shadow.
RNA Markers and Ladders
Our RNA ladders and markers have a size range of up to 9,000 bases. These include the Low Range ssRNA Ladder (NEB #N0364), ssRNA Ladder (NEB #N0362), dsRNA Ladder (NEB #N0363), and microRNA Marker (NEB #N2102).
New England Biolabs offers a selection of highly pure protein standards. Sizes range from 10 to 250 kDa which is ideal for accurate molecular weight determination for a wide range of expressed proteins. We offer a blue prestained protein standard, as well as a colored prestained protein standard with multi-colored bands for easy identification. Standards are provided pre-mixed with loading buffer and reducing agent.
