Question

Which of the following process is helpful in the separation of amniotic fluid and cells?

• A. Blotting technique
• B. Centrifugation
• C. Spectrophotometry
• D. Nano drop

Answer 1

Answer: (B)

Centrifugation

The most common method to separate cellular mixture is centrifugation. In this process, the components are separated on the basis of difference in their densities. Amniocytes (cells from amniotic fluid) are also obtained from the amniotic fluid by the same process i.e. centrifugation.The culture of the amniocytes is centrifuged. The cells being heavier settle down at the bottom which are removed by discarding the debris. So, the correct option is B.
