Mabtech IRIS

Mabtech IRIS™ – Spot analysis reinvented

IRIS is a FluoroSpot and ELISpot reader capable of analyzing four analytes simultaneously with unparalleled accuracy and speed. The system revolves around our novel RAWspot™ algorithm, ensuring accurate spot center detection and thus correct counting. Together with the intuitive software Mabtech Apex™, our readers provide a plug-and-play system that simplifies your workflow. Just load the plate, select the assay, and press "read".

  • ELISpot and FluoroSpot (up to 4 colors) 
  • Precise spot counting 
  • Fixed focus and self-calibrating XY table for a streamlined workflow
  • Intuitive software for a smooth user experience
  • Customizable presets for recurrent experiments

Streamlined workflow

Mabtech IRIS is pre-calibrated for a smooth workflow. Simply insert the plate, select assay type, and press the read button. The entire signal from every spots is recorded so that adjustments can be made after plate reading – you never have to re-read a plate. In addition, the Mabtech Apex™ software offers intuitive layout features and automatic data export to speed up the time from data acquisition to analysis. 




Precise spot counting  

The software for Mabtech IRIS is based on our patented RAWspot™ technology. The RAWspot algorithm is optimized to find the exact location of the spot center. This refined spot center detection is the basis for accurate spot counting and is essential to identify cells secreting multiple analytes in FluoroSpot. 
Mabtech IRIS also delivers a new dimension of spot data – the relative spot volume (RSV) – as RAWspot extracts a 3-dimensional volume for each spot corresponding to the amount of secreted analyte.




Read now, analyze later

After plate reading, you are free to adjust parameters such as brightness, intensity, contrast, and spot size cut-offs without affecting the original data. As IRIS has already recorded the uncompressed signal straight from the camera sensor, changes can be made afterwards without affecting the original data. 
Find out how Mabtech IRIS meets the requirements of CFR21 part 11 (FDA guidelines on electronic records in clinical investigations) here.



Minimized variability

Automated reader configuration and optimized presets minimize user-defined input and ensure an objective analysis independent of the user’s level of experience. Plus, the intuitive software facilitates smooth onboarding. Spot analysis has never been easier.
