Advantages of Plating Method Over Electronic Cell Counting for Cell Analysis and Identification

.In terms of counting cells, what does a plating method accomplish that an electronic cell counting method does not?

The plating method differentiate between live and dead cells (viable cells) while the electronic cell counting method does not.

A plating method is a technique that involves diluting a sample of cells and then spreading them onto a solid culture medium, allowing them to grow and form visible colonies. This method allows for the enumeration of viable cells – cells that are capable of dividing and growing under the given conditions.

On the other hand, electronic cell counting methods use specialized equipment to count cells based on their size, shape, and electrical properties. These methods provide rapid and accurate cell count estimates, but they do not differentiate between living and dead cells.

Therefore, a plating method can accomplish the following things that an electronic cell counting method cannot:

1. Differentiation between live and dead cells: A plating method allows for the selection of viable cells, which can then be used for further analysis or experimentation. Electronic cell counting methods may count both living and dead cells, providing an inaccurate representation of the true cell population.

2. Identification of specific cell types: A plating method can be used to isolate specific cell types from mixed populations. For example, when working with bacteria, selective culture media can be used to isolate specific bacterial strains from a mixed population. Electronic cell counting methods cannot identify or isolate specific cell types.

3. Assessment of clonality: A plating method allows for the determination of clonality (the number of distinct cell populations in a sample). Electronic cell counting methods cannot determine clonality.

In summary, while electronic cell counting methods can provide rapid and accurate cell count estimates, a plating method is required for the selection and identification of viable cells and specific cell types, as well as the assessment of clonality.
