Dual fluorescence detection of two biomolecules simultaneously in the context of a whole cell
Meet Ella, your immunoassay problem solver. Her Simple Plex™ assays are fully automated, multi-analyte immunoassays. And, the coolest part? They’re powered by antibodies from R&D Systems.
SimplePlex™ assays run on Ella - they're like mini, automated ELISAs. Ella’s multi-sample, ready to go cartridges let you run up to 4 immunoassays per sample, all at once. On top of that, Ella just uses 25 μL of sample! Setup only takes 5 minutes, and she'll have your data ready in 60 minutes. Hands-free.
DuoSet® ELISA Development Kits contain the basic components required to develop an immunoassay. They offer an economical alternative to buying separate antibodies and proteins.
