Automated protein analyzer Peggy Sue™

laboratorybenchtop

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! HOW CAN PEGGY SUE HELP YOU? My sample is precious and I don't have enough for other methods like western blot Sometimes you wish you could do more with your small and precious sample. Peggy Sue, our most frugal automated Simple Western system, can run up to 96 data points in one overnight run with as little as 5 µL of sample. She can utilize that limited sample size to the max by allowing you to interrogate those few microliters eight times, such as when analyzing an entire cell signaling pathway in a single run. Imagine all the data you can get from your sample using one automated Simple Western! I need more than size data from my protein analysis Sometimes a band from a western blot is not telling you the entire story about your target of interest. Size-based separation will not be able to resolve phosphorylation isoforms and other post-translational modification. A charge assay (cIEF plus immunodetection) has the power to let you see beyond what's detected by a traditional western blot. Peggy Sue gives you two ways to get separation, identification and quantitation of your sample through Simple Western analysis.
