[Verification Material] Quality Control by Parameter Measurement in iPS Cell Culture Supernatant

Study on Quality Control through Parameter Measurement in iPS Cell Culture Supernatant

Focusing on "cell proliferation," one of the indicators of cell quality, we compared the results of cell proliferation and culture medium component analysis when changing the culture conditions. This is the result data from an experiment where the frequency of medium exchange was set to three conditions during the maintenance culture of iPS cells in a feeder-free environment, followed by three passages. In this verification, we used the cell culture environment analysis device "BioProfile FLEX2." The "BioProfile FLEX2" is a non-invasive, low-sample-volume device that can measure up to 16 items, including metabolites and cell viability, in just 4 minutes and 30 seconds, or 2 minutes with individual modules. 【Product Specifications】 Analysis Items: Glucose/Lactate/Glutamine/Glutamate/NH4+/Na+/K+ Ca++/pH/pO2/pCO2/Total Cell Density/Viable Cell Density/Viability/Cell Diameter/Osmolality Automatic Calibration: 2 hours (fixed)/Time required 2 minutes Operating Environment: Temperature 10–30°C, Humidity 20–85% 【Features】 ■ Simultaneous analysis of up to 16 items ■ Measurement time: as short as 2 minutes, as long as 4 minutes and 30 seconds (depending on measurement items) ■ Measurement of consumption and production rates of major metabolites ■ Compatible with multiple shapes of sample containers ■ Equipped with an auto-sampling function for continuous measurement
