Protocol for Competitive RT-PCR.For quantifying mRNA, we use a competitive RT-PCR protocol with internal standard RNAs. These are added in a defined quantity to the RNA sample prior to the RT reaction. The resulting standard cDNA is coamplified with the s - [Read Competitive RT-PCR Protocol]
In this protocol, sample and competitor RNAs are reverse transcribed (separately) in a pilot experiment. A constant amount of sample RT product is then combined with a 2-logserial dilution of competitor RT product for PCR. Procedure provides an approximate copy number for the sample, which is then fine-tuned by repeating the experiment with a series of twofold dilutions of competitor. The experiment includes controls for sample-to-sample variations in RT efficiency. - [Read Competitive RT-PCR: Estimation of Copy Number Protocol]
The first step in competitive RT-PCR is the synthesis and purification of the synthetic competitor. This is an RNA molecule designed to be reverse-transcribed and PCR-amplified with the same efficiency as the endogenous transcript of interest. Once the competitor molecule has been prepared, as described in this protocol, competitive PCR can be carried out. - [Read Competitive RT-PCR: Preparation of Competitor RNA Protocol]

Ultrafiltration is an alternative to ethanol precipitation for the concentration and desalting of nucleic acid solutions. It requires no phase change and is particularly useful for dealing with very low concentrations of nucleic acids. This protocol describes the use of the Microcon cartridge, a centrifugal ultrafiltration device, to concentrate and desalt nucleic acid solutions. - [Read Concentrating and Desalting Nucleic Acids with Microconcentrators Protocol]
Concentration of DNA by Ethanol Precipitation Protocol. Adapted fromBruce A. Roe, Department of Chemistry and Biochemistry, The University of Oklahoma, Norman, Oklahoma. Usually 2.5 - 3 volumes of ethanol and/or acetate solution is added to the DNA in a microcentrifuge tube. This is then put into an ice-water bath for at least 10 minutes. The precipitation is performed by incubation at -20C overnight. - [Read Concentration of Oligo DNA by Ethanol Precipitation Protocol]
Conditional ablation of stat3/socs3 discloses the dual role for reactive astrocytes after spinal cord injury. The current protocol demonstrates that reactive astrocytes play a crucial role in wound healing and functional recovery by using mice with a selective deletion of the signal transducer and activator of transcription-3 (STAT3) or suppression of cytokine signaling-3 (SOCS3) under the control of Nestin gene promoter/enhancer (STAT3N–/–, SOCS3N–/–). - [Read Conditional Ablation of Stat3 Socs3 Discloses the Dual Role for Reactive Astrocytes]
Protocol for configuration, column construction, and column packing for a capillary liquid chromatography system. Protocol describes a procedure for adapting conventional HPLC systems to provide accurate low-flow rates (0.4-4 µl/min) and gradients required to operate slurry-packed capillary columns. A key component of this system is a commercial axial-beam longitudinal flow cell that can be fitted to several commercial UV detectors. - [Read Configuration Column Construction Column Packing for Capillary Liquid Chromatography]

The following protocol can be used for the development of stable cell lines expressing GFP fusion proteins. Although optimal transfection procedures (e.g., calcium phosphate, electroporation, or FuGENE 6 [Roche Applied Science]) vary depending on cell type, this general transfection procedure has been successful for stable transfection of HeLa, A-431, U2OS, BHK, and HT1080 cells. - [Read Constructing and Expressing GFP Fusion Proteins]

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.
