There are many ways to adapt cell lines to serum-free media. Five methods are presented that are designed for adapting hybridomas to a protein-free medium. These protocols may require some modifications for your particular cell line and conditions. - [Read Adapting Cells to a Serum-Free Environment Protocol]
4 strains of E. coli are used in these studies: JM101 for M13 infection and isolation, XL1BMRF'for M13 or pUC-based DNA transformation, and ED8767 for cosmid DNA transformation. To maintain their respective F' episomes necessary for M13 viral infection, JM101 is streaked onto a M9 minimal media plate and XL1BMRF' is streaked onto an LB plate containing tetracycline. ED8767 is streaked onto an LB plate. These plates are incubated at 37degC overnight. For each strain, 3 ml. of appropriate liquid.. - [Read Bacterial Cell Maintenance Protocol]

Protocol should be viewed as a starting point for systematic optimization of transfection mediated by lipofecting agents. Once a positive signal has been obtained from a transfected plasmid carrying a standard reporter gene, optimal conditions for transfection can be established by systematic variation of parameters such as the initial cell density, the amount and purity of DNA, the media and serum, and the time of exposure of the cells to the cationic-lipid-DNA complex. - [Read DNA Transfection Mediated by Lipofection Protocol]

A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.
The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
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.
This protocol describes the electroporation of the BMH 81-17 mut S strain that is recommended for tranformation of the site directed mutagenesis of dsDNA (See Protocol on Site-Directed Mutagenesis on Double Stranded DNA). BMH 81-17 mut S are a mismatch repair defective (mut S) Escherichia coli strain. The probability that the two mutations will cosegregate during the first round of DNA replication is increased in this strain.
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.
