TIRM is a optical technique for monitoring the instantaneous separation distance between a microscopic sphere & a flat plate. Changes in distance as small as 1 nm can be detected. Includes information on: Scattering Intensity I is Related to Elevation h ; apparatus. - [Read Total Internal Reflection Microscopy]
This protocol fixes and prepares embryos for in situ hybridization to visualize transcript expression patterns. It is a modification of the method developed by Tautz and Pfeifle for whole-mount in situ analysis of embryos. Use of the standard hybridization protocol on RNAi-treated embryos results in high background staining, which makes visualization of transcript expression patterns practically impossible. The following modifications eliminate this problem and allow visualization of transcript. - [Read Transcript In Situ Hybridization of Whole-Mount Embryos for Phenotype Analysis of RNAi-Treated]
Protocol details the preparation of fluorescently labeled target samples and hybridization of these samples to a microarray of Agilent inkjet-deposited cDNAs. The procedure requires a minimum of 5 mg of purified total RNA as starting material. Includes: First Strand cDNA Synthesis; Second Strand cDNA Synthesis; cDNA Cleanup and Precipitation; In vitro Transcription; Cleanup and Quantification of in vitro Transcribed RNA; Fluorescent Labeling of the Target Samples. - [Read Transcript Profiling by Microarray Analysis Protocol.]

The following procedure is for simultaneous transfection and plating of RAW 264.7 cells. This protocol results in approximately 50% to 70% cell viability, and of those viable cells, 20% to 40% are transfected when using pEYFP-N1
from Clontech. Include: Procedure for Splitting Cells before Transfection; Procedure for Preparing Lipofectamine 2000 and DNA; Preparation of RAW 264.7 Cells for Transfection. - [Read Transfecting and Plating RAW 264.7 Cells with Lipofectamine 2000 Protocol]
This protocol describes two transfection methods for expressing GFP-tagged actin in primary neurons. The lipid reagent DOTAP (Roche Diagnostics) method produces actin-GFP-expressing hippocampal neurons that survive well during long periods in culture. The calcium phosphate method can be used to transfect neurons that have already been growing on coverslips in vitro. Transfected cells suitable for imaging can be obtained in cultures up to 15 days in vitro. - [Read Transfecting Cultured Hippocampal Neurons with an Actin-GFP Plasmid]

DEAE-dextran is generally used to obtain a burst of transient expression of cloned genes after transfection of mammalian cells. Many variants of the technique have been described, all of which seek to maximize the uptake of DNA and to minimize the cytotoxic effects of DEAE-dextran. In this protocol cells are exposed briefly to a high concentration of DEAE-dextran-DNA and then to chloroquine diphosphate, which is a facilitator of transfection. - [Read Transfection Mediated by DEAE-Dextran: High-efficiency Method Protocol]
Transfection of primary leukocytes has traditionally been a challenging but much desired protocol. It allows not only the analysis of cells in a more natural state to a cell line system, it enables the direct comparison of, for e.g. transcriptional activity using luciferase reporters, in immune cells taken from genetically-altered mice. In addition, importantly it allows for "rescue experiments" in knockout cells & the ability to over-express or reconstitute wild-type and/or mutated constructs. - [Read Transfection of Bone Marrow-Derived Mast Cells for Transcription Factor Luciferase Reporter Assays]
This protocol describes transfection of plasmid DNA into primary hippocampal neurons using DNA/calcium-phosphate (CaPO4) coprecipitation. The precise pH of the transfection medium and the incubation time of cells with the coprecipitate are critical for reproducible and efficient transfection. Once these parameters are optimized for a given plasmid, the method is easily adapted for transfection of other established cell lines. - [Read Transfection of Hippocampal Neurons with Plasmid DNA Using Calcium Phosphate Coprecipitation]
Protocol describes a method for the delivery of siRNAs into mammalian cells in the absence of reporter plasmids. This is best achieved with transfection reagents developed for the delivery of antisense oligodeoxynucleotides. The quantities of reagents given below are calculated for the transfection of one well of a 24-well plate. - [Read Transfection of Mammalian Cells with siRNA Duplexes Protocol]

Protocol describes the transfer of RNA from agarose gels to neutral or positively charged nylon membranes, using upward capillary flow of neutral or alkaline buffers. RNA becomes covalently fixed to positively charged nylon membranes during transfer in alkaline buffers. However, treatment by UV irradiation or heating is required to fix RNA to neutral membranes. - [Read Transfer and Fixation of Denatured RNA to Membranes 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.
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.
