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]

Bradford Assay Method - http://research.cm.utexas.edu/bkitto/Kittolabpage/Protocols/Biochemistry/Bradford.html

Category: Protein Protocols: Protein Quantitation Concentration Protocols: Bradford Protein Assay Protocols

The bradford dye-binding assay is a colorimetric assay for measuring total protein concentration. It involves the binding of Coomassie Brilliant blue to protein. There is no interference from cations nor from carbohydrates such as sucrose.
Detergents such as sodium dodecyl sulfate and triton x-100 can interfere with the assay, as well as strongly alkaline solutions.

Includes a general overview of the procedure and preparation of the standards in the protocol. - [Read Bradford Assay Method]

Removal of Small Fragments of Nucleic Acid from Preparations of Plasmid DNA by Centrifugation - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3916

Category: Nucleic Acid Purification Protocols: DNA Isolation Protocols: DNA Plasmid Preps Protocols

Contamination of plasmid DNA by fragments of DNA and RNA is reduced to an acceptable level by centrifugation through 1 M sodium chloride. This method was devised by Brian Seed when he was a graduate student at Harvard University. - [Read Removal of Small Fragments of Nucleic Acid from Preparations of Plasmid DNA by Centrifugation]

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.

Drosophila Cell Transfection Protocol

A simple Drosophila tissue culture cell transfection method.

Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA

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.

Probe Preparation for 22 x 40 mm DNA Microarrays Protocol.

Acid Guanidinium Thiocyanate RNA Isolation Phenol Chloroform Extraction

A single step RNA isolation protocol using Phenol Chloroform Extraction and Acid Guanidinium Thiocyanate. This RNA isolation method uses the fact that guanidinium thiocyanate can simultaneously lyse the cells and inactive cellular RNAses during the initial RNA isolation step allow a single step in the method.

In Vitro Translated Xenopus Mos Kinase Assay Protocol

In Vitro Translated Xenopus Mos Kinase Assay Protocol. In response to progesterone, immature Xenopus oocytes mature to eggs that can be fertilized. The Mos protein kinase is essential for oocyte maturation, most likely due to its ability to activate the MAP kinase cascade. This MAP kinase cascade eventually leads to the activation of Cdc2/cyclin B and entry into M phase. In this protocol, tagged Mos kinase is translated in vitro, immunopurified, and used in a kinase assay.

Antibodies Phage Expression Protocol Using 96-well Microtiter Plates

A Phage display expression protocol for antibody expression in 96-well microtiter plates.

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.
