Protocol describes the trypsinization of cells in monolayer culture to facilitate subculture or harvesting. To avoid cross-contamination of cells, it is important for each cell line to be subcultured independently. No more than one cell line should be in the tissue culture hood at any one time. - [Read Trypsinization of Cells Grown in Monolayer Protocol]
Protocol describes how to generate a plasmid construct (pBAIT) that expresses a target protein fused to the bacterial LexA protein. PBAIT is cotransformed into yeast with a lexAop-lacZ reporter plasmid carrying the bacterial lacZ gene under the control of the lexA operator. The recipient yeast strain contains a chromosomally integrated leu2 reporter gene, also under the control of the lexA operator. - [Read Two-hybrid Systems Stage 1: Characterization of a Bait-LexA Fusion Protein Protocol]
In this stage of the protocol, a mammalian cDNA library constructed in a plasmid such as pJG4-5 is transformed into yeast strains containing pBAIT and the lexAop-lacZ reporter plasmid. PJG4-5 expresses the cloned cDNAs from a cassette containing a transcriptional activation domain and other moieties under the control of the yeast GAL1 promoter. - [Read Two-hybrid Systems Stage 2: Selecting an Interactor Protocol]

Simple method for growing Neurospora and for isolation of DNA that may be performed in two days from start to finish. The growth of mycelia in Petri plates eliminates the need for large numbers of flasks when growing many cultures for DNA isolation. - [Read Ultra-Fast Method of DNA Extraction from Neurospora Protocol]
No cell culture problem is as universal as that of culture loss due to contamination. All cell culture laboratories and cell culture workers have experienced it. Culture contaminants may be biological or chemical, seen or unseen, destructive or seemingly benign, but in all cases they adversely affect
both the use of your cell cultures and the quality of your research. Contamination problems can be divided into three classes: Minor annoyances, Serious problems, Major catastrophes. - [Read Understanding and Managing Cell Culture Contamination Protocol]
Background and methods to study plant transport. Includes new methods to study protein trafficking in plant cells, includes: Identification of protein sorting pathways in non purified samples; Localization of organelle proteins by isotype tagging/isotype-coded affinity tag; Coupling of chemical genomics and proteomics; Top down mass spectrometry; Compartment-specific markers to aid in the purification of organelles. - [Read Understanding Protein Trafficking in Plant Cells Through Proteomics]
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.
Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.
This Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA protocol describes the production of probes labeled with the fluorescent dyes, Cy3 and Cy5, following the synthesis of cDNA from human mRNA and the hybridization of the probes to DNA microarrays.
