An oligodeoxynucleotide primer hybridized to mRNA is extended by an RNA-dependent DNA polymerase to create a cDNA copy that can be amplified by PCR. Depending on the purpose of the experiment, the primer for first-strand cDNA synthesis can be specifically designed to hybridize to a particular target gene, or a general primer such as oligo(dT) can be used to prime cDNA synthesis from essentially all mammalian mRNAs - [Read Amplification of cDNA Generated by Reverse Transcription of mRNA Protocol]
Protocol uses a single thermostable RNA polymerase to perform high-specificity RT-PCR. A high-temperature RT reaction is followed by PCR amplification of the cDNA using a single thermostable poymerase, the GeneAmp AccRT RNA PCR enzyme from Applied Biosystems. The high temperature of the RT reaction enhances the specificity of primer binding and also reduces secondary structure in the template, thereby increasing the efficiency of polymerization. - [Read Amplification of RNA: High-Temperature Reverse Transcription and DNA Amplification with a Magnesium]
Protocol provides a quick way to assay for RNA-dependent RNA polymerase (RdRP) activity in crude protein samples. RdRP transcription products remain at the origin during paper chromatography. - [Read An Assay for RNA-Dependent RNA Polymerase Activity Protocol]
Protocol is for bidirectional, blunt-end cloning of DNA fragments. The target DNA is PCR amplified and 3'-extensions are polished with Pfu DNA polymerase. The amplicon is ligated to a blunt-ended plasmid DNA, and the products of the ligation reaction are used to transform competent Escherichia coli. A restriction enzyme is added to the ligation reaction to relinearize any self-religating vector DNA. - [Read Bidirectional Cloning of PCR Products Protocol]
Here, the DNA-RNA hybrids synthesized in Stage 1 are converted into full-length double-stranded cDNAs. The primers for synthesis of second-strand cDNA are created by RNase H, which introduces nicks into the RNA moiety of the cDNA-mRNA hybrids. E. coli DNA polymerase I extends the newly created 3'-hydroxyl termini, using the first-strand cDNA as a template. - [Read Construction of cDNA Libraries Protocol]

Protocol for in vitro mutagenesis using double-stranded DNA templates. Two oligonucleotides are used to prime DNA synthesis catalyzed by a high-fidelity thermostable polymerase on a denatured plasmid template. The two oligonucleotides both contain the desired mutation and occupy the same starting and ending positions on opposite strands of the plasmid DNA. - [Read In Vitro Mutagenesis Using Double-stranded DNA Templates: Selection of Mutants with DpnI]
General guidelines for long-PCR conditions and enzyme mixtures. Efficient long-PCR results from the use of two polymerases: a non-proofreading polymerase is the main polymerase in the reaction, and a proofreading polymerase (3' to 5' exo) is present at a lower concentration. Includes: For PCR with low-complexity templates (e.g., plasmid and cosmid inserts); For PCR with moderate-complexity templates (e.g., bacterial genomic DNA); For PCR with high-complexity templates (e.g., human genomic DNA). - [Read Long-PCR Reagents and Guidelines]
Quick and reliable method to analyze meiotic segregation patterns in Coprinus cinereus using the polymerase chain reaction. The advantages of this method include: 1. The tissue is grown and lyophilized in the same tube, which facilitates the simultaneous analysis of many segregants. 2. Only one extraction step is necessary. 3. The markers are scored by gel electrophoresis, thereby bypassing Southern analysis. - [Read Method to Analyze Meiotic Segregation Patterns in Coprinus cinereus Using PCR]
3' Rapid Amplification of cDNA Ends RACE Using PCR Protocol. This protocol contains the steps for 3' end rapid amplification of mRNA by PCR. The first-strand cDNA is synthesized from total or poly(A+) RNA by priming from the poly-A tail of the mRNA using a oligo (dT) adaptor primer. The cDNA is then amplified via PCR using a gene-specific primer and an adaptor primer.
