Protocol describes the trypsinization of cells in monolayer culture to facilitate subculture or harvesting. To avoid cross-contamination of cells, it is important for each cell line to be subcultured independently. No more than one cell line should be in the tissue culture hood at any one time. - [Read Trypsinization of Cells Grown in Monolayer Protocol]
This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.
The protocol gives general considerations for the design of targeting vectors for transgenic mice. The protocol shares tips in the design of knock-out and knock-in vectors and some of their strategies for producing homologously recombined embryonic stem cells.
