Nucleic acid standards include molecular rulers with evenly spaced banding patterns (DNA ladders), EZ Load standards premixed with loading buffer, and specialty products, such as pulsed field standards.
This guide to Bio-Rad's complete line of protein and DNA standards for electrophoresis and blotting is organized into tabbed sections for both protein and DNA standards; the protein standards are divided into sections based on applications.
Reference information includes specifications for each set of standards, gel migration charts, recommended applications, a photograph of the standards run on a gel, and the molecular mass or pI of each standard band.
Bio-Rad molecular rulers are available in several convenient size ranges and increments for sizing single- and double-stranded DNA. Visually distinct reference bands make it easy to determine the size of your sample DNA.
