Ella does it better than standard manual ELISAs. Her multi-sample, ready to go cartridge lets you run 4 immunoassays per sample all at once. On top of that, Ella only uses 25 µL of sample! Setup takes 5 minutes, and she'll have your data ready in 60 minutes. The best part? Ella's Simple Plex assays are powered by R&D Systems so you'll only get top-notch data.
