Thermo Fisher, 4311320, Hi-Di™ Formamide, 25 mL

Hi-Di™ Formamide, 25 mL is designed for preparation of DNA sequencing and fragment-analysis samples before electrokinetic injection into compatible capillary electrophoresis systems. This package contains 25 mL of highly deionized Hi-Di formamide, a liquid used to resuspend or dilute prepared samples for injection. Formamide provides a denaturing sample environment used in electrophoretic workflows, while the highly deionized formulation supports the sample preparation requirements of Applied Biosystems genetic analyzers. The reagent is used after appropriate sequencing or fragment-analysis reaction and cleanup steps as the sample-loading matrix rather than as the sequencing enzyme or fluorescent labeling chemistry. It enables preparation of a consistent liquid sample for transfer into the instrument injection workflow. The product is supplied as a single 25 mL volume, distinct from multi-vial 5 mL presentations of the same reagent. It ships on dry ice and is designated for research rather than diagnostic use. The exact package size is useful when planning high-throughput Sanger sequencing or DNA fragment-analysis sample preparation across multiple plates.
