Two ways to get separation, identification and quantitation

Peggy Sue™ lets you separate and analyze proteins by size or charge from 2-440 kDa either by immunoassay or total protein. Got small sample volumes or starting materials? No problem. She uses as little as 0.2 µg/µL of protein in just 5 µL of sample, and runs up to 96 samples in one experiment. Charge ahead and do more with Peggy Sue!
