CASY Model TT Cell Counter + AnalyZer E L E C T R I C A L C U R R E N T EXCLUSION ECE BASED CELL ANALYSIS
ELECTRICAL CURRENT EXCLUSION CASY Model TT Cell Counter + Analyzer R&D Easy and fast adaptation to an unlimited number of applications combined with a non-invasive measurement principle, are key features that make the CASY Model TT an indispensable tool for cell culture analysis in R&D. Different precision measurement capillaries, together with cell-specific setups, allow for the measurement of all types of mammalian cells, as well as bacteria, yeast, algae, parasites, pollen and sperm. MS-Excel bases data transfer software provides complete documentation and flexible data evaluation to follow the metabolic state of cells during any type of cell culture experiment. P r o c e s s Development Product Description The CASY Cell Counter + Analyzer System Model TT determines not only the cell number but also the size distribution and viability of a cell sample quickly and reliably. In addition, the aggregation level in the cell sample is determined and automatically included in the determination of the cell concentration. The basic results provided are: Cell concentration Cell viability Cell volume Cell aggregation Cell debris Improving cell culture processes requires fast and accurate data about the quality of the cells. In addition to cell concentration, CASY Model TT monitors cell viability, cell size and aggregation. Also, cell debris has become an increasingly important quality control parameter in process control. With a measurement time of only 10 seconds for a single measurement, different parameters that indicate the state of the cell culture can be thoroughly tested in a short time.

ELECTRICAL CURRENT EXCLUSION CASY Model TT Cell Counter + Analyzer H i g h R e s o l u t i o n Size Distribution The high resolution size distribution offered by CASY -Technology ensures that the size of every individual cell or particle passing through the measuring pore can be detected. A clear-cut differentiation between cell debris, dead cells, viable cells and cell aggregates is provided, and even volume differences of a fraction of a femtoliter can be detected. Cell volume is a very sensitive parameter that can be used to detect changes in a cell culture. Therefore, a visualized finger-print of the metabolic state of the cell culture is provided. Typical CASY High Resolution Size Distribution Technology CASY Model TT is based on the international accepted reference method for cell counting, ISO 13319. In addition, the system is equipped with an advanced method for digital pulse processing called Pulse Area Analysis. This technique is used to get complete information from the signals created when a cell or particle passes through the high precision measuring pore in a low voltage field. Each single object is scanned with a frequency of one million measurements per second, resulting in up to hundreds of readings per cell. Thus, the complete time course of the signals is taken into account when analyzing samples. Pulse Area Analysis provides a unique, high resolution recording of the cell size distribution and an outstanding dynamic measurement range. It is the basis for the dye-free, non-invasive determination of cell viability. Pulse Area Analysis How it works

ELECTRICAL CURRENT EXCLUSION CASY Model TT Cell Counter + Analyzer Applications With the CASY Model TTC there are no limitations concerning the type of cell and the type of application. The system allows to follow each type of cell culture experiment and is recommended to be used for the quality control, the improvement and the longterm-monitoring of biological processes. Typical applications include: Counting of all types of cells Control of cell seeding Success or failure of many cell culture experiments depend on seeding the cells in the correct concentration and in good shape at the very beginning. Precise determination of the cell concentration and the state of the cells therefore is indispensable for cell seeding control. Determination of cell proliferation Cell proliferation strongly depends on the conditions used to grow up the cells. Even minimal changes in the composition of the medium or the addition of stimu lating or inhibiting substances can effect the rate of cell proliferation considerably. Therefore the measurement of cell proliferation is a standard method to optimize cell culture processes. Determination of cytotoxic effects on cells 125 Measuring of Cytotoxicity: IC50 - Determination With a size range of 0.7 to 160 µm, nearly all types of cells can be measured. This includes bacteria, yeast cells, algae cells, protozoa and all types of mammalian cells. The CASY high resolution size distribution also provides important information about the metabolic state of the cells, in addition to counting cells.

Based on the high resolution size distribution, as well as Electrical Current Exclusion, CASY Model TT determines both effects of toxic substances on cells independently.
