The Q-Phase is a holographic microscope from Telight. The output is the phase image where the light delay (phase shift) across each part of the sample is stored as a quantitative value in the corresponding image pixels (Quantitative Phase Imaging). This allows for direct measurement of the cell dry mass distribution in real-time.

Q-phase is optimised for label-free live-cell imaging and automated cell culture analysis. It is also equiped with a widefield fluorescence modality. Q-phase is particularly suited to long-term live-cell imaging and has extremely low phototoxicity. Applications include cell morphology, cell death, cell cycle, and migration studies. The image acquisition software SophiQ performs cell segmentation and tracking and calculates parameters such as cell dry mass, density, area, growth speed, and euclidean distance.

SophiQ is also available on Dolly, our dedicated analysis machine.

Sample preparations is important for QPI - the media or buffer cannot have a meniscus. So it requires specific slides/dishes.
We have special lids for 35 mm dishes and 24-well-plates.

Located in MCBB room L1.22.
