Standards are integral part of every experiment as a general check of the electrophoresis run and for valid gel-to-gel comparisons. DNA and protein standards calibrate molecular weight, isoelectric point, or base pair size on agarose and polyacrylamide gels.
Nucleic Acid Standards include molecular rulers with evenly spaced banding patterns, EZ Load standards premixed with loading buffer, and specialty products, such as pulsed field standards.
Bio-Rad Nucleic Acid Standards Include • Molecular Rulers Molecular rulers are DNA standards with precisely defined size intervals between bands. Bio-Rad provides three types of molecular rulers: standard, EZ Load, and AmpliSize rulers. • Molecular Mass Rulers Bio-Rad precision molecular mass rulers allow accurate DNA quantitation in gels, making them ideal for densitometry or image analysis. The EZ Load precision molecular mass ruler is ready to load. • Pulsed Field Standards Bio-Rad standards for pulsed field applications can be used for applications from FIGE separation of cosmid inserts to separation of the largest chromosomes.
