NEBtools brings New England Biolabs’ most popular web tools to your iPhone and iPad, allowing you to plan your experiments from anywhere. Use Enzyme Finder to select a restriction enzyme by category, recognition sequence, overhang or name to find information on that enzyme. Determine buffer and reaction conditions for experiments requiring two restriction enzymes using the Double Digest Finder. When using either of these tools, look for Time-Saver and HF enzymes for the ultimate in convenience. Use Tm Calculator to calculate optimum annealing temperature for PCR primers when using NEB polymerases and buffers. Use NEBioCalculator to convert DNA or RNA mass to moles, calculate insert ligation amounts, convert OD to concentration, and calculate basic dilution and molarity. NEB Tools for iOS also enables quick and easy access to NEB Technical Support by phone, email, or web when you need it.

What’s New

Version 2.4.0

Version 2.4.0 of NEB Tools updates the on-board restriction enzyme data used by Double Digest and Enzyme Finder. The update also includes the new naming scheme for NEBuffers reflecting the new BSA-free formulations. Enzyme supplement information was also updated.

Great for quick reference!

If you're like our lab, and not everyone has the catalogue, then this app is great. When you can't find your catalogue because someone "borrowed" it... again... just pull out the app!

Downsides are it's obviously not going to be as in depth as the catalogue or full online resources, but it's a quick reference guide. It's also only with the new buffers now, so if you're stocked up on buffers 1-4 then go ahead and grab the catalogue.
