Ella: Your Next Generation ELISA

Ella's combination of performance and workflow brings your immunoassays to the next level. In just 90 minutes you get highly reproducible validated assay data with no manual steps. The assay performance behind that data includes sub-picogram level sensitivity, 4+ logs of dynamic range and reproducibility that rivals the best laboratory automation. All in a compact package that doesn't break your budget or your lab bench.

ELISA results. One hour.

See how Simple Plex eliminates all the challenges of traditional ELISAs:

  • Save time with automated assays run on Ella in just an hour
  • Get quantitative, reproducible data using 25 µL with a 4-5 log dynamic range
  • Eliminate cross-reactivity by detecting each analyte in separate parallel channels

  • Can expired cartridges be run on the Ella?

    The Ella instrument is not programmed to reject expired cartridges, however we can only support the performance of cartridges within the expiration date.

  • What is the minimum sample volume required for Simple Plex assays?

    A minimum of 50 µL of volume is required, regardless of dilution factor.

  • What is the expiration date of a Simple Plex cartridge?

    Simple Plex cartridges expire one year from the date of manufacture.

  • What is the expiration date of Simple Plex controls?

    Lyophilized controls are stable for up to 12 months from the date of receipt when stored at 2-8 °C. Reconstituted controls are stable for up to 6 months from date of preparation when stored at ≤ -70 °C. Storage at -20 °C is not recommended.

Simple Plex Technology

Ella does immunoassays in a microfluidic Simple Plex cartridge. It's like using a pre-kitted immunoassay, except everything's pre-loaded on the cartridge—even the calibration curve! All you need to do is add your sample and buffers and put the cartridge in Ella.

The immunoassay part works like this: sample runs through a microfluidic channel that binds your protein of interest. Next, Ella washes off unbound analyte and adds a detection reagent. Because each channel has three Glass Nano Reactors (GNRs) coated with a capture antibody, you get triplicate answers for each sample. Answers are then generated from the factory-calibrated standard curve that comes with every cartridge. Sound familiar? It's the same immunoassay you're used to, just without the errors that come with traditional assays.
