This procedure capitalizes on the asexual/sexual reproductive cycle of yeast cells. Laboratory yeast strains can be maintained indefinitely by asexual reproduction as one of two haploid mating types, MATa or MAT{alpha}. - [Read Genome-Wide Analysis of Protein-Protein Interactions Using a Two-Hybrid Array]

Category: Tetrahymena Protozoa Protocols

Mature Tetrahymena cells of opposite mating types are starved under appropriate salt conditions. The mating types are then combined to costimulate through cell-cell interaction. Loose pairs and then firm, irreversible pairs of cells of opposite mating types form. This method consistently results in a high percentage of pairing (usually greater than 80%) and good synchrony. - [Read Induction of Conjugation in Tetrahymena Protocol]

Microneedles attached to micromanipulators are used in the dissection of tetrads, isolation of zygotes from populations of mating haploid cells, and manipulation of individual cells. - [Read Making a Tetrad Dissection Needle Protocol]

When more than one bait will be used to screen a single library, significant time and resources can be saved by performing the interactor hunt by interaction mating. In this protocol one strain is transformed with library DNA and the transformants are collected and frozen in aliquots. - [Read Performing a Hunt by Interaction Mating Protocol]

Protocol for quantitative mating assay. - [Read Quantitative Mating Assay Protocol]

Category: Laboratory Model Organisms Protocols

Feeding euplotids with algae can lead to asynchronous cell starvation and vastly different cell sizes within a culture. Asynchronous starvation also leads to different levels of mating competence. Furthermore, algal pigment remnants can interfere with many applications (e.g., fluorescence microscopy). - [Read Refeeding Marine Euplotids with Bacteria Protocol]

Category: Tetrahymena Protozoa Protocols

Protocol describes a method for transformation of the Tetrahymena using electroporation. The vector is electroporated into cells after mating, where it is incorporated into the DNA of developing macronuclei. Because T. thermophila can be propagated indefinitely without conjugation, transformation of the macronucleus provides a way to obtain stable somatic transformants. DNA vectors transformed using this protocol include those containing drug-resistant versions of Tetrahymena genes. - [Read Transformation of Tetrahymena thermophila by Electroporation Protocol]

Category: Mouse Protocols: Mouse Reproductive System Surgery Protocols

Protocol describes a method for vasectomy in which the vas deferens is accessed through the abdominal wall. Mice are ready for mating after ~10-14 days. Vasectomized males can be bred with fertile females to obtain plugs for timed matings. The pseudopregnant females can then be used for oviduct and uterine transfers. For an alternative protocol, see Vasectomy for Generation of Sterile Males: Access via Scrotal Sac. - [Read Vasectomy for Generation of Sterile Males: Access via Abdominal Wall Protocol]

Category: Drosophila Protocols: Drosophila Genetics Protocols

Protocol describes the general procedure for creating mutations in the DNA of Drosophila by exposure to X-rays. Irradiation of cells with X-rays creates double strand breaks (DSBs) in DNA. Mutations introduced in the DNA of germ line cells (sperm) are propagated by mating the exposed males to virgin females. The progeny of this cross can be mated to each other so that a percentage of the subsequent offspring will have two copies of the same mutant allele. - [Read X-Ray Mutagenesis of Drosophila Protocol]
