A Method for Isolation of Chloroplast DNA and Mitochondrial DNA from Sunflower - http://pubs.nrc-cnrc.gc.ca/ispmb/ispmb16/16183-2.pdf

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

The protocol includes: organelle isolation, deoxyribonuclease treatment, lysis, deproteinisation and a final DNA purification with sodium dodecyl sulphate and potassium acetate. The organelle DNA yield is 5–10 micrograms per gram of tissue and the DNA is fully restrictable. The technique is inexpensive and appropriate for the isolation of multiple samples of organelle DNA from a small amount of tissue. - [Read A Method for Isolation of Chloroplast DNA and Mitochondrial DNA from Sunflower]

In this protocol, the DNA-binding capacity of Wizard MagneSil particles is used to capture and release a consistent amount of DNA (100 ng) across a wide range of samples. At the end of the procedure, the DNA is eluted into 100 µl Elution Buffer to give a final concentration of 1 ng/µl, relieving the need for postpurification DNA quantitation. - [Read DNA IQ Isolation of Genomic DNA from Stains and Buccal Swabs Protocol]

Category: Nucleic Acid Purification Protocols: DNA Isolation Protocols

Protocol for fungal DNA isolation. The key elements in this prep are (1) the use of young lyophilized mycelial mats....young mats (4 days growth for C. carbonum)...yield less contaminating carbohydrates and other misc. junk (2) lots of proteinase K in the extraction buffer to kill Dnases (final =0.3mg/ml). - [Read Fungal DNA Isolation Protocol]

Immunoprecipitation: Preclearing the Lysate Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4535

Category: Immunology: Immunoprecipitation Protocols: Protein Immunoprecipitation Protocols

To reduce backgrounds and to improve the signal-to-noise ratio, an antibody that does not recognize the antigen being studied can be added to the lysate and processed as for a normal immunoprecipitation. Any nonspecific proteins that might contaminate the final immunoprecipitation step are presumably removed with this irrelevant antibody. - [Read Immunoprecipitation: Preclearing the Lysate Protocol]

Category: Chromatography Protocols: Immobilized Metal Ion Affinity Chromatography Protocols

Protocol is specifically for the further enrichment of phosphopeptides from a phosphotyrosine pull-down. This is the final step for the preparation and enrichment of phosphopeptides using immobilized metal affinity chromatography (IMAC) for the identification of the phosphopeptides by liquid chromatography tandem mass spectrometry (LC-MS/MS). - [Read Preparation and Enrichment of Phosphopeptides from Phosphotyrosine Protocol]

Subfractionation of Low-Density Lipoprotein (LDL) - http://www.axis-shield.com/densityhome/optiprep/M11.pdf

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols

In the routine method described in this protocol, chylomicron-free plasma is adjusted to 12% (w/v) iodixanol and the sample, essentially fills an approx 3 ml tube for a near-vertical rotor. During the centrifugation VLDL, LDL and HDL particles and also plasma proteins migrate from all parts of the sample to their final buoyant density banding position in the self-forming density gradient. - [Read Subfractionation of Low-Density Lipoprotein (LDL)]

Populational Analysis of Genomic DNA Protocol

A protocol on the populational Analysis of genomic DNA.

Single Stranded Plasmid DNA Isolation 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.

Genomic DNA Labeling of Microarrays Protocol

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 Polymerization Protocol using GTP and GMPCPP

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.

Probe Preparation for 22 x 40 mm DNA Microarrays Protocol.

Immobilized Antigen Phage Antibody Selection Protocol

A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.

DNA Ligation Protocol

The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
