The preparation of expressional cDNA libraries for use in the yeast two-hybrid system is quick and efficient when using the dedicated Clontechâ„¢ product, the MATCHMAKER Library Construction and Screening Kit 3. This kit employs SMART technology for the amplification of full-length cDNAs, in combination with cloning using homologous recombination. - [Read Isolation of Plant Transcription Factors Using a Modified Yeast One-Hybrid System]
A discontinuous gradient of iodixanol is used in which the crude mitochondrial fraction is layered beneath the preformed
gradient. In this protocol the osmolality of the gradient is approx 600 mOsm and the crude mitochondrial fraction is loaded in 40% iodixanol rather than 50% iodixanol. - [Read Isolation of Yeast Mitochondria in aPre-Formed Iodixanol Gradient]
Protocol describes the use of agarose plugs for isolation of yeast artificial chromosome (YAC) DNA. The DNA can then be run on a pulsed-field gel and used for microinjection to produce transgenic mice. - [Read Large-Scale Preparation of Agarose Plugs of Yeast DNA Protocol]
Protocol for large-scale yeast transformation. Includes: Yeast Cell Preparation; Large Scale Transformation; To plate on solid medium; To select in liquid. - [Read Large-Scale Yeast Transformation Protocol]
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]
Protocol for measuring volume. Material required includes: Microscope, Hemacytometer and coverslip, Suspension of yeast. - [Read Measuring Volume 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]
Method to restart stuck fermentation. Includes: Select and rehydrate active dry wine yeast; activate the rehydrated yeast with nutrients and sugar; start the fermentation and add the stock wine in batches. - [Read Method to Restart Stuck Fermentation]
This protocol describes the isolation of microsomal Endoplasmic Reticulum (ER) membranes from yeast cells. Includes: Spheroplast Formation and Microsome Purification. - [Read Microsome Preparation from Yeast Cells Protocol]
DNA prepared by PCR-mediated gene disruption can be used to transform yeast in gene replacement experiments. This protocol uses two primers, tailed with approximately 50 nucleotides homologous to the gene of interest, that target insertion of the PCR product to that locus. Each primer ends with a universal sequence that is designed to amplify various selectable markers from plasmid templates. - [Read PCR-Mediated Gene Disruption: One-Step Method 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.
DNA microarrays are an ordered arrangement of DNA molecules complementary to genes of interest that are "spotted" by robotic equipment onto a glass slide substrate. The expression of genes in cells can be monitored with microarrays by preparing cDNA from the mRNA of cells of interest and measuring the hybridization to the microarray. This protocol describes the labeling of genomic DNA for use as a probe for hybridization to the cDNA spotted on the array.
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 Immunoâ„¢ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.
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.
