Mabtech IRIS 2

Streamlined workflow

Mabtech IRIS 2 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 2 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 2 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, contrast, spot intensity, and spot size thresholds without affecting the original data. As IRIS 2 has already recorded the uncompressed spot signals straight from the camera sensor, changes can be made later without affecting the original data. The fast and responsive Apex software has multiple file-save formats available simplifying data handling.

We take quality control seriously at Mabtech. Read about the different regulatory requirements (such as CFR21 part 11, EU Annex 11) Mabtech IRIS 2 meets 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. 

Ready for automation

Mabtech IRIS 2 was designed to make the analysis of larger projects as painless as possible. In addition to self-calibration, responsive software, and easy data handling, IRIS 2 allows for robotic plate loading. Our reader can be part of an automated workflow with a robotic arm or be fully integrated into a larger automated setup. Each automation solution is unique, and we’ll be here to help every step of the way.

Performance qualification  

Our readers are reliable tools that can be trusted to deliver accurate results over an extended period of use. However, it’s essential to demonstrate that the readers maintain acceptable performance over time, especially when facing internal or external review for regulatory compliance. Mabtech’s Performance Qualification (PQ) plates provide a solution for verifying that our instruments fulfill quality specifications and to ensure reproducibility. The PQ plates allow users to conduct a series of quantitative and qualitative tests making it easy to identify any incorrect or inconsistent operation of the reader. By using PQ plates, our instruments can be confidently validated providing peace of mind knowing that experiments are accurate and reliable.

Different sections of the PQ-plate:
1.    Tests focus and RAWspot algorithm in FluoroSpot
2.    Tests LED light intensity in FluoroSpot
3.    ELISpot test

Count foci with FociSpot

FociSpot is our new assay platform that includes both kits and a new analysis capability of Mabtech IRIS 2, allowing for automated counting of foci in a 96-well plate format. In FociSpot, foci are detected with immunostaining using virus-specific mAbs and a precipitating substrate reaction similar to ELISpot.
