Category: Chromatography Protocols: Ion Exchange Chromatography Protocols

Protocol for selection of an ion exchanger: Determining the pI of a protein using isoelectric focusing. The choice of whether to use an anion or a cation exchanger should be based on knowledge of the stability of the protein, and the binding properties of the target protein and other molecules present. - [Read Selection of an Ion Exchanger Protocol]

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.

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.

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.

Microinjection Pipette Pulling Protocol

A simple protocol for microinjection pipette pulling.

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 Fragment Purification from Polyacrylamide Gels Protocol

A simple protocol for the purification of DNA fragments from Polyacrylamide Gels.

Constructing Random-Peptide Libraries for Phage Display

The protocol describes the construction of a large (10^8 to 10^10) primary random peptide phage library in fUSE5 or f88-4 strains.

Absorption Spectroscopy and Quantification of Filamentous Phage Protocol

Unlike spherical phage, such as T4 and λ, which have roughly equal weight ratios of protein to DNA, filamentous phage have about six times more protein than DNA; the protein therefore contributes substantially to the absorption spectrum.

3' Rapid Amplification of cDNA Ends RACE Using PCR Protocol

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.
