This section provides guidelines and general procedures for routine subculturing, thawing, and freezing of cells in culture.
Note that cell culture conditions vary for each cell type. The consequences of deviating from the culture conditions required for a particular cell type can range from the expression of aberrant phenotypes to a complete failure of the cell culture. We therefore recommend that you familiarize yourself with your cell line of interest, and closely follow the instructions provided with each product you are using in your experiments.
Methods & Cell Culture Protocols
- Concentrating Cells: A procedure to concentrate cells from suspension culture or to resuspend cells from a monolayer culture.
- Counting Cells in a Hemacytometer: How to count and calculate the number of cells from a stock flask or culture dish.
- Counting Cells in a Countess™ II: How to count and calculate the number of cells using an automated cell counter.
- Guidelines for Maintaining Cultured Cells: Learn what is subculture and when to do it, review media recommendations for common cell lines and how to dissociate cells as well as the benefits of using TrypLE™ as an alternative to trypsin.
