New England Biolabs (NEB) has expanded its line of reagents for sample preparation with the introduction of NEBNext Quick DNA Sample Prep Reagent Set 2 and Master Mix Set 2, both suitable for library construction for Roche's 454 GS FLX Titanium and GS Junior instruments.

NEB said that the new products provide all the necessary enzymes and buffers for fast fragment library preparation. The Master Mix Set further streamlines the workflow, reducing the number of vials by one third.

NEBNext products are a series of highly pure reagents that facilitate sample preparation for downstream applications, such as next generation sequencing.

All reagents undergo stringent quality controls and functional validation by sequencing, ensuring maximum yield, convenience and value. Reagents are available for each step of the library construction workflow, including end-repair, dA-tailing, adapter ligation and amplification.

Available as reagent sets, master mixes or modules for the three leading next generation sequencing platforms, the full range of NEBNext reagents offer convenience and customisation of workflow. Additionally, NEB offers NEBNext dsDNA Fragmentase, an enzyme-based solution for fragmentation of DNA.
