We count cells by manual methods,
Using the counting chamber,
Plating & colony forming unit count.
We let them be counted automatedly,
Using electrical resistance,
Flow cytometry & image analysis.
Then there is this indirect method too,
Using spectrophotometry we count,
Or even by the impedance microbiology.
Cell counting methods used in Animal Cell Culture include the above three main categories and then seven sub-categories are divided among the three chief categories.
There are two manual counting methods:
a. using the counting chamber for counting each one individually, and
b. plating and CFU (Colony Forming Unit) count.
Three automated counting methods are there:
a. using electrical resistance,
b. flow cytometry, and c. image analysis.
Two indirect counting methods are there too:
a. using a spectrophotometer, or
b. count by impedance microbiology
