Calcium phosphate forms an insoluble precipitate with DNA, which attaches to the cell surface and is taken into the cells by endocytosis. The protocol is easily adapted for use with other types of cells, both adherent and nonadherent. This protocol is a modified version of a method published by Jordan et al. (1996) who rigorously optimized calcium-phosphate-based transfection methods for Chinese hamster ovary cells and the 293 line of human embryonic kidney cells. - [Read Calcium-phosphate-mediated Transfection of Eukaryotic Cells with Plasmid DNAs]

This protocol describes the isolation of fibroblasts from mouse embryos. Mouse embryonic fibroblast (MEF) cells are used as a feeder layer for the culture of mouse embryonic stem (ES) cells to help maintain them as pluripotent stem cells. The inhibition of ES-cell differentiation provided by the MEF feeders appears to be due to their production of leukemia inhibitory factor (LIF). - [Read Isolation and Freezing of Primary Mouse Embryonic Fibroblasts (MEF) For Feeder Plates]
Tissue subcellular fractionation and protein extraction for use in mass-spectrometry-based proteomics. Although many methods exist for fractionating proteins, the method described here can capture the majority of subcellular fractions simultaneously at reasonable purity. The scalability of this method makes it amenable to small samples, such as embryonic tissues, in addition to larger tissues. The protocol described is for the general fractionation and extraction of proteins from organs / tissue - [Read Tissue subcellular fractionation and protein extraction for use in mass-spectrometry-based proteomic]
MEF feeders are prepared weekly to provide a substrate for undifferentiated embryonic stem (ES) cells. Primary MEF cells are thawed, established in culture, treated with mitomycin C to halt their proliferation so they cannot overgrow the ES cultures, and then replated onto dishes convenient for ES cell culture. This protocol can also be used to prepare feeder cells from STO fibroblast cell lines. - [Read Preparation of Mouse Embryonic Fibroblast (MEF) Feeder Plates Protocol]

This protocol describes the preparation of feeder cells from MEF cells or from the STO mouse fibroblast cell line. The cells are rendered mitotically inactive by treatment with {gamma}-irradiation. The feeder layers can then be used to maintain embryonic stem (ES) cells in the undifferentiated state. - [Read Preparing Feeder Cell Layers from STO or Mouse Embryo Fibroblast (MEF) Cells 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.
