No special treatment is required to prepare a lysate for the active collection. The following procedure should be used for long-term storage of lambda clones in the archival collections. The phage are diluted in media containing 7% DMSO and frozen at -80 degrees C. - [Read Long Term Lambda Phage Storage Protocol]
Media and Culture of Yeast Protocol- https://catalog.invitrogen.com/index.cfm?fuseaction=iProtocol.unitSectionTree&treeNodeID=E5192D47CE9B0776DB7D136C34ED148A&objectid=6673ABA6C2DB2E4E7564EDFA26589256
The yeast, Saccharyomyces cerevisiae, has become an important organism in molecular, biochemical, and genetic analysis. The organism has specific requirements for growth under a variety of conditions. The media, both liquid and solid, simple, define, and complex are describe in this unit. Also included are methods for handling, storing, and shipping stock of yeast. - [Read Media and Culture of Yeast Protocol]
Media for Culture of Mammalian Cells Protocol- https://catalog.invitrogen.com/index.cfm?fuseaction=iProtocol.unitSectionTree&treeNodeID=9E662B6F09C1BB8FBC47FC2A7E61A8A3&objectid=66739B890A55AC13354418E67F28E693
The culture medium is an essential component of the in vitro environment and must be selected or designed with care. This protocol provides guidelines for design of serum-containing and serum-free media, selective and specialty media, and media for growth under special conditions such as soft-agar growth. - [Read Media for Culture of Mammalian Cells Protocol]
A simple and inexpensive chamber for regulating gaseous environment of small culture plates, such as those used for culture of preimplantation embryos, can be constructed using disposable media-filtration devises such as Corning’s 115-ml system. The following is a description of how to make such a device. - [Read Mini-Chamber for Regulating Gaseous Environment During Culture]
Mounting media for immunohistology must be compatible with the detection method used. A suitable non-aqueous mounting medium is DPX. - [Read Mounting Samples in DPX Protocol]

Protocol for the preparation of ion-exchange chromatography column. Ion-exchange chromatography (IEC) can be used as a crude step in a protein purification scheme, or, with proper preparation, as a high-resolution step. If high resolution is desired, considerable care should be taken during column preparation, choice of IEC media, and column packing. - [Read Preparation of an Ion-Exchange Column 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.
