UltraClear™ Sequencing Reaction Clean-Up Kit

The Advantage is Clear : Sigma’s UltraClear™ Sequencing Reaction Clean-Up Kit

The UltraClear Sequencing Reaction Clean-Up Kit offers a rapid and simple method for the clean-up of DNA sequencing reactions in a 96-well format. The UltraClear plate uses ultrafiltration membranes to separate low molecular weight contaminants,such as unincorporated dye terminators, dNTPs, and residual salts from the sequencing reaction products.
