CASY Cell Counting Technology - Advantages

Advantages

Since the cell viability is determined by electric current exclusion, viability dyes such as Trypan blue and Propidium iodide are not needed. Hence, cell viability determination need no longer be a terminal experiment. This advantage permits subsequent tests using the cells such as viability after a further time interval.

The given result will be very accurate because not only are all steps performed robotically, but are high throughput(e.g. a million events/second).

CASY technology it is fast but also reliable and reproducible because of features such as the multi-channel analyzer for detecting and analyzing the pulse height generation. In fact, a channel means the pulse counted in a particular energy. In the past, single channel analyzers were used the instruments. They can count the pulse in a narrow range only. So, they can analyze the cells for one or few times at the set frequency only. Once the electric current is changed during the cell transfer, it could not be detected. This can use not only a much time for analysis but also inaccurate cell counting result. However, for the multi- channel analyzer, it can scan the entire energy range and the pulses in each channel. As there are more than 500, 000 channels for a cell counting, once a cell is pass through the measuring pore, there would be a lot of channel monitoring for 1 cell. As a result, the speed of CASY technology to obtain the information of cells can be very high.
