Wes Automated Western Blot System Imager

ProteinSimple Imager Wes Automated Western Blot System

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. Unlike traditional western blots, 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!


Traditional immunoassays, like western blot, often require too much of your precious sample. You end up having to pool samples together or be content with getting just a few data points per experiment. With Wes you only need 3 µL of sample per capillary, so you can maximize the data you get per experiment. Imagine all the data you can get from your sample!
