Hybridization of Oligonucleotide Probes in Aqueous Solutions Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3883

Category: Nucleic Acid Modification Protocols: Nucleic Acid Labeling Protocols

Hybridization is carried out in conventional aqueous solvents at a temperature well below the predicted melting temperature. Nonspecific hybrids are then removed by washing at high stringency in buffers containing quaternary salts. Tetramethylammonium chloride (TMACl) is used with probes that are 14-50 nucleotides in length, whereas tetraethylammonium chloride (TEACl) is used with longer oligonucleotides. - [Read Hybridization of Oligonucleotide Probes in Aqueous Solutions Protocol]

Ligating Plasmid and Target DNAs in Low-melting-temperature Agarose Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3929

Category: Cloning Protocols

Protocol for ligating plasmid and target DNAs in low-melting-temperature agarose. Ligation in low-melting-temperature agarose is much less efficient than ligation with purified DNA in free solution and requires a large amount of DNA ligase. The method is used chiefly for rapid subcloning of segments of DNA in dephosphorylated vectors and assembling recombinant constructs. - [Read Ligating Plasmid and Target DNAs in Low-melting-temperature Agarose Protocol]

PCR Genotyping from Tail DNA Protocol - http://genetics.med.harvard.edu/~cepko/protocol/mike/P4.html

Category: Genetics and Genomics: Genotyping Protocols: PCR Genotyping

Protocol for PCR genotyping from tail DNA. This protocol works well for a variety of genes and primer pairs including Tg and KO alleles. Oligonucleotide melting temperatures between 60° and 65° seem to work well. - [Read PCR Genotyping from Tail DNA Protocol]

Phenol-based Protocol Isolation of DNA Fragments from Low-Melting Temperature Agarose - http://wheat.pw.usda.gov/~lazo/methods/101/101lmtagar.html

Category: DNA Protocols: DNA Extraction Protocols: Agarose Gel DNA Extraction Protocols

Phenol-based Protocol Isolation of DNA Fragments from Low-Melting Temperature Agarose. Reference: Favre, D. 1992. Biotechniques vol. 13. - [Read Phenol-based Protocol Isolation of DNA Fragments from Low-Melting Temperature Agarose]

Preparation of DNA for Pulsed-field Gel Electrophoresis: Isolation of Intact DNA from Yeast - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3235

Category: Nucleic Acid Electrophoresis Protocols: Pulsed Field Gel Electrophoresis Protocols

Protocol for preparation of DNA for pulsed-field gel electrophoresis: isolation of intact DNA from yeast. Yeast cells are first treated enzymatically to break down the cell walls and then resuspended in low-melting-temperature agarose plugs. The DNA is liberated by infusing the plugs with lysis buffer and proteases. This method is used to prepare both conventional and artificial yeast chromosomes. - [Read Preparation of DNA for Pulsed-field Gel Electrophoresis: Isolation of Intact DNA from Yeast]

Real-Time PCR Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4112

Category: PCR Protocols: Real-Time PCR Protocols

Protocol uses FAM-(6-carboxy-fluorescein) or JOE-(6-carboxy-4', 5' -dichloro-2',7' -dimethoxy-fluorescein) labeled LUX (Light Upon eXtension) primers, which can quantify 100 or fewer copies of the target DNA in a background of nonspecific templates, over a broad dynamic range of less than 100-107 copies. It uses uracil deglycosylase (UDG) to minimize the risk of carryover contamination, and includes a melting curve analysis of the product. - [Read Real-Time PCR Protocol]

Recovery of DNA from Low-melting-temperature Agarose Gels: Enzymatic Digestion with Agarase Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4026

Category: Nucleic Acid Electrophoresis Protocols: DNA Electrophoresis Protocols: DNA Electrophoresis in Agarose Gels Protocols

A fragment of gel containing a band of DNA is excised and digested with agarase, which hydrolyzes the polymer to disaccharide subunits. The released DNA is then purified by phenol extraction and ethanol precipitation. The method works well for DNAs ranging in size from <5 kb to >20 kb. - [Read Recovery of DNA from Low-melting-temperature Agarose Gels: Enzymatic Digestion with Agarase Protocol]

Recovery of DNA from Low-melting-temperature Agarose Gels: Organic Extraction Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4025

Category: Nucleic Acid Electrophoresis Protocols: DNA Electrophoresis Protocols: DNA Electrophoresis in Agarose Gels Protocols

DNA fragments separated by electrophoresis through gels cast with low-melting-temperature agarose are recovered by melting the agarose and extracting the resulting solution with phenol:chloroform. The protocol works best for DNA fragments ranging in size from 0.5 kb to 5 kb. - [Read Recovery of DNA from Low-melting-temperature Agarose Gels: Organic Extraction Protocol]

Retrieval of DNA Fragments from Pulsed-field Gels following DNA Concentration Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4035

Category: Nucleic Acid Electrophoresis Protocols: Pulsed Field Gel Electrophoresis Protocols

Protocol for retrieval of DNA fragments from pulsed-field gels following DNA concentration. DNA contained in a slice of low-melting-temperature agarose is first concentrated by electrophoresis into a high-percentage agarose gel, and then isolated by treatment with agarase. The resulting DNA preparation is purified by microdialysis. - [Read Retrieval of DNA Fragments from Pulsed-field Gels following DNA Concentration Protocol]

Paraffin Embedding Protocol

Paraffin Embedding Protocol for molecular profiling. This Paraffin Embedding Protocol describes the processing of the tissues into sections following ethanol fixation. Molecular profiling (MP) is a technique that is used to visualize the global patterns of RNA expression or protein expression in various cell types and disease processes.
