DO Monitoring in 96-Well Plate
PhoxyPlate 96 O
These 96-well plates have optical oxygen sensors integrated at the bottom of each well. With the PhoxyCube system DO in the wells can be recorded non-invasively over time. The plates are put on the readout unit and oxygen measurements are taken non-invasively through the transparent well bottoms. The whole PhoxyCube system with PhoxyPlates can be placed in an incubator and is therefore ideally suited for high-throughput screenings, cell and microbial culture and respiration measurements. Take your analyses to the next level and monitor changes in real time!
- Non-invasive oxygen monitoring in each well
- Ready-to-use disposable
- Visualization of kinetics in real time
- Use in incubator
- Ideal for screenings, cell cultivation & more
- Multitude of parallel respiration measurements
Applications
Simultaneous O2 & pH Monitoring in Cell Culture
Monitoring oxygen and pH levels is critical in cell culture. Changes in O2 concentration or pH can lead to metabolic stress and alter cell functions. With the PhoxyCube system these two parameters can be measured in real time; optimal culture conditions can be ensured and inaccurate experiment results avoided.
Dose-Response Study in Pharmacological Research
The measurement of dose-response relationships is essential for understanding the effects of pharmacological agents on cellular functions. Changes in cell metabolism also show in changes in the cells’ oxygen uptake rate. With the PhoxyCube system and the PhoxyPlate 96 O highly parallelized oxygen measurements and dose-response studies can easily be performed. Adverse effects will show immediately in the online oxygen measurement data.
Respiration Measurements with PhoxyCube
PhoxyCube is the ideal tool for respiration measurements and research. Oxygen can be monitored in a multitude of samples simultaneously over time. Whether it is germination in plant seeds or respiration of small aquatic organisms, whatever your research subject is, with PhoxyCube any changes in oxygen consumption will be visible immediately.
