Category: PCR Protocols: cDNA Synthesis Protocols

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]

Category: Reporter Gene Assays: B-Galactosidase Assay Protocols

This assay is used when working with phage vectors carrying the beta-gal gene. If the cloning event disrupts a normally functional copy of the gene in the vector the resulting plaques would appear clear in the assay. If the phages contain a functional beta-gal gene they will form blue rings around their plaques. Any strain which is not an overproducer of beta-gal will work as indicator host bacteria; a single chromosomal copy of the gene is not a problem. - [Read Assay for Phage Containing the Beta-galactosidase Gene]

Category: Yeast Protocols: Yeast Genetics Protocols: B-Galactosidase Assay Protocols

This assay is used when working with phage vectors carrying the beta-galactosidase gene (often used for immunological screening). If the cloning event disrupts a normally functional copy of the gene in the vector the resulting plaques would appear clear in the assay. If the phages contain a functional beta-galactosidase gene they will form blue rings around their plaques. Any strain which is not an overproducer of beta- galactosidase will work as indicator host bacteria. - [Read Assay for Phage Containing the Beta-galactosidase Gene Protocol]

Category: PCR Protocols: Reverse Transcriptase RT-PCR Protocols

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]

Category: Fungi Protocols: Fungi Genetics Protocols

Standard operating procedure for the determination of tissue fungal burden utilizing quantitative real time polymerase chain reaction (QPCR). This standard operating procedure will provide information on how to assess fungal tissue burden of infected animals by use of a single copy (FKS) or multicopy gene (18s RNA) to assess the number of fungal cell nuclei present. - [Read Determination of Tissue Fungal Burden Utilizing Quantitative Real Time Polymerase Chain Reaction]

Category: Nucleic Acid Modification Protocols: DIG Biotin Labeled Probes Protocols

Protocol describes a high sensitivity indirect detection procedure for DIG-labeled hybridization probes.  The procedure uses the components of the HNPP Fluorescent Detection Set to form a fluorescent precipitate of HNPP (2-hydroxy-3-naphthoic acid-2’-phenylanilide phosphate) and Fast Red TR at the site of hybridization.  This procedure can be used to detect single copy sequences as small as 1 kb on human metaphase chromosomes.

Category: Plant Biology Protocols: Plant Genetics Protocols

To accurately predict the activity of a transgene it is critical to understand its location and dynamics in the 3-D interphase nucleus. Developed in situ methods to visualize transgenes (including single copy genes) & their transcripts during interphase from different tissues & plant species. These techniques reduce the time necessary for characterization of transgene integration by eliminating the need for time-consuming segregation analysis and extend characterization to the interphase nucleus - [Read In Situ Methods to Localize Transgenes and Transcripts in Interphase Nuclei]
