One of the most important, but frequently overlooked, cell culture procedures is testing cultures for microbial contamination, especially mycoplasma. It is critical for every cell culture laboratory to only use cell lines that have been
carefully screened for mycoplasma. Fortunately, there is a simple fluorochrome DNA staining test that can detect both mycoplasma and virtually any other prokaryote contaminants. - [Read Mycoplasma Detection Using DNA Staining Protocol]
Describes the steps in detail to isolate and expand neural stem cells in the form of neurospheres from tissue dissections of the post-natal mouse brain. Procedures for the long term passage of neurospheres and the cryopreservation of neurospheres are also provided. In addition to the guidelines and tips for generating neurosphere cultures, we describe the method to prepare neurospheres for analysis by light microscopy. - [Read Neural Stem Cell Culture: Neurosphere Generation, Microscopical Analysis and Cryopreservation]
The cytotoxic effect of chemicals upon mammalian cells, such as BALB/c 3T3 and HepG2, in culture is measured by highest tolerated dose (HTD), cell viability (Neutral Red) and total cell protein (coomassie blue). - [Read Neutral Red Cytotoxicity Assay Protocol]
Remove medium from culture container, rinse with PBS, expose cells to trypsin, incubate, stop trypsin activity by adding serum containing medium, dissociate cells, dilute and
return to incubator. - [Read Passage of Adherent Cell Lines (subculture).]
RAW 264.7 cells are a macrophage-like, Abelson leukemia virus
transformed cell line derived from BALB/c mice. For routine maintenance in culture (passage), cells are seeded at a confluence of approximately 10% (1 x 106 and 3 x 106 cells in 100-mm and 150-mm plates, respectively) and grown to a confluence of approximately 80%. This procedure requires the cells to be split every two days. - [Read Passage Procedure for RAW 264.7 Cells]
Protocol describes a method to determine the presence of plasmid DNA in an Agrobacterium culture. Compared to selection of transformed Agrobacterium, which can be ambiguous and normally takes several days for resistant colonies to appear, the approach described here is both rapid and accurate. - [Read PCR Analysis of Agrobacterium Protocol]

Protocol reproducibly generates competent cultures of E. coli that yield 1 x 108 to 3 x 108 transformed colonies/µg of plasmid DNA. The protocol works optimally when the bacterial culture is grown at 18°C. If a suitable incubator is not available, a standard bacterial shaker can be set up in a 4°C cold room and regulated to 18°C. - [Read Preparation and Transformation of Competent E. Coli: "Ultra-Competent" Cells Protocol]

A Single Stranded Plasmid DNA Isolation Protocol describing the production and isolation of single-stranded DNA (ssDNA) using bacteriophagemid-containing bacteria and helper phage. Infection of the host cells with helper phage allows for packaging of ssDNA into bacteriophage. The ssDNA can then be isolated from phage particles.
A single step RNA isolation protocol using Phenol Chloroform Extraction and Acid Guanidinium Thiocyanate. This RNA isolation method uses the fact that guanidinium thiocyanate can simultaneously lyse the cells and inactive cellular RNAses during the initial RNA isolation step allow a single step in the method.
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.
Histone H1 Kinase Activity Assay Protocol. This protocol describes assaying kinase activity of a putative kinase using Histone H1 as the substrate. Histone H1 is the canonical kinase substrate in this type of assay. Phosphorylation of Histone H1 is assessed by SDS-Polyacrylamide gel electrophoresis followed by autoradiography.
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.
