Protocol describes the use of PCR to screen for bacteria that carry recombinant plasmids. The PCR can be carried out using the same primers as for amplification of the cloned insert. To determine the orientation of the insert, a third, insert-specific primer that is asymmetrically distanced from the clonal insertion site can be used. - [Read Colony PCR Protocol II]
Direct method for determining efficiency in yeast. The plating efficiency of a strain is a measure of the percentage of cells in a culture that are capable of forming colonies (colony forming . - [Read Determining Plating Efficiency in Yeast: Direct Method]

This test is designed to detect irreversible toxic effects on both cell growth and survival, by the evaluation of colony-forming (CF) efficiency, in hepatoma cell lines derived from man, rat and mouse. - [Read Hepatoma Cell Cultures as In Vitro Models for Hepatotoxicity]
Information and tips on how to avoid pitfalls and keep out of trouble in the Neurospora lab. Includes: Culture, incubation, storage, and disposal; Stock preservation; Spore and colony counts; Making crosses and recovering progeny; Use of heterokaryons for allelism tests; Use of unordered asci to estimate the relation of translocation breakpoints to centromeres. - [Read How to Avoid Pitfalls and Keep Out of Trouble in the Neurospora Lab]
For all the transgenic or other mouse researchers out there who have had to explain why colony infections are not just bad for the welfare of the animals concerned, but may invalidate the ongoing studies as well. - [Read Natural Pathogens of Laboratory Mice and Rats]
Protocol allows the isolation and enumerate Aspergillus spp spores in air. Includes: Sampling Procedure; Sampling Location; Selection of Sampling Time; Sampling Steps; Laboratory Procedure; Enumerating the Colony Forming Units. - [Read Sampling of Aspergillus spp Spores in Air Protocol]
The following colony PCR protocol has been designed to be performed in individual reaction tubes. We usually test three colonies from each transformation along with a wild-type control. A series of five different PCR tests are performed on each colony to - [Read Single tube confirmation PCR protocol]
Some yeast strains are unstable (e. g., small YAC-bearing strains) and need to be repurified by streaking on an agar plate and then verifying the genetic content of the isolated colony before proceeding. In cases where the strain is unstable, plan to streak the cells onto the selective medium to retain the desired stock, (however, most strains can be streaked onto the complete medium, YPD). - [Read Streaking Yeast Stocks Protocols]
Protocol for yeast colony PCR. This method for yeast colony PCR is used to test for the presence of target sequences in cells. - [Read Yeast Colony PCR 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 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.
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.
