Side angle scatter (SSC) is measured by flow cytometers. What does a SSC measurement indicate?

A cell commits to division or quiescence during the M phase of the eukaryotic cell cycle.

You are measuring viability of your cell population with trypan blue. You observe 10, 15, 12, and 11 clear cells and additional 2, 4, 5, and 2 blue cells in the appropriate squares of the hemocytometer. If you loaded 0.02ml of you cell suspension and 0.02ml of trypan blue, and you have 5mL of cell suspension, how many viable cells do you have?

Sterilization removes, destroys or inactivates all life of any kind from an object or material.
