Simple Westerns just got even simpler

Wes™ lets you separate and analyze proteins by size from 2-440 kDa. He also gets you down to pg-level sensitivity with just 3 µL of starting material. Got a lot of samples and no time? No problem. Wes runs up to 25 samples in 3 hours flat and gives you quantitative, size-based data including total protein. Don't wait to discover, get going today with Wes!

Meet Wes, a protein characterization problem solver

Proteins are complex, but protein characterization shouldn't be. Are you struggling with methods that aren't quantitative? Are you spending all of your precious sample just to optimize your assay? Is the throughput inadequate? Are you waiting days to get your data? Watch this video to find out how Wes can be your protein characterization problem solver.
