2.2. How Pelleting Cells Works

• Step-by-Step Breakdown: Describe the process of pelleting cells in a clear and concise manner.
  1. Cell Suspension Preparation: Briefly explain how cells are prepared in a liquid medium (e.g., culture medium, buffer solution).
  2. Centrifugation: Explain how the cell suspension is placed in a centrifuge tube and subjected to high-speed spinning.
  3. Pellet Formation: Describe how the centrifugal force causes the cells to migrate to the bottom of the tube, forming a compact "pellet."
  4. Supernatant Removal: Explain how the liquid above the pellet (the supernatant) is carefully removed, leaving the cell pellet behind.
• Key Parameters Affecting Pelleting:
  • Centrifugal force (g-force or RPM)
  • Centrifugation time
  • Temperature
  • Type of centrifuge rotor

• Table: Common Centrifugation Parameters

  Parameter	Typical Value	Explanation
  Centrifugal Force (g)	100 – 2000 g	The force applied to the sample; higher g-force results in faster pelleting.
  Time	5 – 30 minutes	The duration of centrifugation; longer times may be needed for smaller or less dense cells.
  Temperature	4°C or Room Temperature (25°C)	Used to maintain cell viability and prevent degradation; often chosen based on the specific cell type.
