Assay measures cell viability. It is a two-color fluorescence assay that simultaneously determines Live cell number and Dead cell number. This protocol is designed for use with the GEMINI XS Microplate Spectrofluorometer, a multi-well plate scanner with dual excitation/emission capabilities, but the assay is also adaptable for flow cytometry and fluorescence microscopy. Includes: Cell Culture; Preparation for the Assay; Live/Dead Assay; Reading the Plate; Data Analysis; Alternative protocol. - [Read Live/Dead Assay for Cell Viability Protoco]
Yeast strains may be stored indefinitely at low temperatures (-80 degrees C). Two archiving methods are presented below. In Method A , the cells are grown on a plate, while in Method B the cells are grown in liquid culture. - [Read Long Term Storage of Yeast Stocks Protocol]
This simple cell culture-based cytotoxicity test (in which cell viability is determined by uptake of the dyes ethidium bromide and fluorescein acetate) has been developed as a general test for acute toxicity. - [Read LS-L929 Cytotoxcitiy Test]
Protocol describes a method for isolation and stimulation of lymphocytes. Leukocyte-rich plasma is collected from whole blood and then centrifuged through Ficoll-Hypaque. The collected cells are resuspended in growth medium containing various mitogens to stimulate growth. - [Read Lymphocyte Isolation and Culture Protocol]
For cells grown in tissue culture, the most useful method of lysis is treating with detergents, as described in this protocol. Non-ionic detergents, such as NP-40, solubilize the plasma and intracellular membranes, break many weak intermolecular bonds, and solubilize most of the commonly studied protein antigens. RIPA lysis buffer may be used as a more rigorous extraction buffer to release all but the insoluble proteins of the cell and to break most weak noncovalent interactions. - [Read Lysing Tissue-Culture Cells for Immunoprecipitation 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]

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]
Exponentially growing cells are asynchronous with respect to the cell cycle stage. Detection of cell cycle-related events is improved by enriching the culture for cells at the stage during which the particular event occurs. Methods for synchronizing cells are provided here, including those based on morphological features of the cell. - [Read Methods for Synchronizing Cells at Specific Stages of the Cell Cycle]
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]

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.
