This protocol has been used successfully to 15N or 13C/15N label our proteins using our pET1120/BL21(DE3) expression system: Preparing M9 minimal media begins with preparing a 5x stock solution of M9 salts. Generally, M9 salts contain a nitrogen source in the form of NH4Cl. Since we want to add a labeled nitrogen source, our 5x salts are prepared minus NH4Cl. Standard 5 X M9 Minimal Media salts minus nitrogen source For 1L 5xM9 salts: - [Read Expression Protocol in M9 Minimal Media via T7 Promoter]

Compendium of protocols for using Aspergillus nidulans in genetic, molecular, and cell biological investigations, originally written for members of my research group. It also summarizes our common growth media and nutritional supplements, many of which originally appeared elsewhere but now are difficult to locate. Includes: Growth and storage of Aspergillus nidulans conidia; Nutritional supplements for our common auxotrophies; Double mutants; Mitotic mapping - assigning genes to chromosomes; etc - [Read Fundamentals of Growth, Storage, Genetics and Microscopy of Aspergillus nidulans Protocols]

High-throughput and sensitive assay to measure yeast cell growth: a bench protocol for testing genotoxic agents. Method is highly sensitive, provides quantifiable data and offers high-throughput screening capability. Starting with the treatment of cells with different doses of damaging agents, pre-prepared growing media containing 96-well plates are inoculated and cell population is automatically monitored every 10 min for 48 hours. - [Read High Throughput and Sensitive Assay Measure Yeast Cell Growth Protocol]

Protocol describes a plate method that gives very good yield for cloning. Includes: T-TYN Media + Mg+2; T-TYN Plates; T-TYN Top Agarose. - [Read Lambda DNA Preparation 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.
