Functional Screening Facility

The High Throughput Screening (HTS) facility of ICGEB counts over 10 years’ experience in the development of innovative, image-based High Throughput Screening (HTS) approaches dedicated to unraveling the complexities of molecular pathways that drive human diseases. At the core of the HTS-BSL2 facility is an automated platform that integrates a suite of sophisticated instruments, including a confocal microscope, multimodal plate readers, and automated liquid handling systems, all designed to streamline and enhance the screening process.

📍 The “Functional Screening Facility” is located at ICGEB laboratories in Area Science Park.

Automated Liquid Handling System

Microlab STAR
The Hamilton Microlab STAR is an automated liquid handling system for high accuracy, precision, and repeatability from sub-microliter to large volumes. The smooth interplay between software and mechatronics, coupled with an intuitive user interface makes the liquid handling of the Microlab STAR easy to program and less error prone.
The system configuration includes a single working arm, Modular Arm MPH, equipped with:

  • 8 individual 1000 μl channels (volume range 0.5 – 1000 μl)
  • 384-channel multichannel head (volume range 0.2- 50 μl with 384 tips and 1-300 μl with Rocket tips)
  • iSwap robotic transport arm for integrating the plate sealer
  • CO-RE gripper for transporting plates and lids on the worktop
  • capacitive sensors for active liquid level recognition
  • independent movement with asymmetric spreading

High-Throughput Screening System

Operetta CLS High-Content Analysis System

Operetta CLS is a high throughput microplate imager for high-content analysis (HCA). It can acquire, analyze and manage fluorescence, brightfield and digital phase contrast images. The combination of high power LED excitation with fast, precise mechanics and one large format sCMOS camera enables fast imaging. Controlled by Harmony software it offers a seamless workflow, for reliable discrimination of phenotypes even in complex cellular models.
