Cell size analysis

The change of cell size is a key feature and is commonly measured in cell research. Normally it will be measured in these experiments: cell transfection, drug test and cell activation assays. Countstar® provides statistical morphology data, such as the sizes of cells, within 20s.

Countstar® automated cell counter can give the morphological data of cells, including circularity and diameter histograms. Countstar® BioMarin can provide information on the major and minor axis lengths.

In the Suspension of Mixed Cells, Each Cell Is Measured Separately

The control software of the full range of Countstar®automated cell counters provide a parameter setting mode that allows users to count a specific cell in a mixture through simple parameter setting. The figure shows the culture of CHO cells. The counting of large polyploid cells is required in this process. The green circles are living large polyploid cells, while the yellow circles are dead large cells.

Cell Transfection Experiment

After the plasmid transfection, the diameter of CHO cells increases. From the diameter histogram, we can see that the cell diameter increases from 14μm to 19μm after transfection.


Statistical data of major and minor axis lengths of algae   After being optimized specifically for algae research, Countstar® BioMarine software can provide the major and minor axis lengths of algae. The following figure shows the data of the major and minor axis lengths of algae cylindrotheca fusiformis.
