AFLP For Positional Cloning - http://www-ciwdpb.stanford.edu/publications/methods/aflp.html

Category: Plant Biology Protocols: Plant Genetics Protocols

AFLP was designed as a highly sensitive method for DNA fingerprinting to be used in a variety of fields. We are using this technology to generate DNA based markers for cloning genes involved in phototropic responses in higher plants that have only been identified genetically by mutant phenotype. Protocol includes: Generate polymorphic recombinant F2 (or F3) population; Isolate genomic DNA; Restriction of DNA; Ligation of adapters; Pre-amplification of template DNA; AFLP-PCR; etc. - [Read AFLP For Positional Cloning]

AFLP: not only for fingerprinting, but for positional cloning - http://www-ciwdpb.stanford.edu/publications/methods/aflp.html

Mannie Liscum and Paul Oeller. Department of Plant Biology. Carnegie Institution of Washington, Stanford. AFLP technology is used here to generate DNA based markers for cloning genes involved in phototropic responses in higher plants that have only been i - [Read AFLP: not only for fingerprinting, but for positional cloning]

Biogenesis and Function of Peroxisomes and Glycosomes - http://students.washington.edu/mdminer/pabio_551/kessler1.pdf

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols: Peroxisome Isolation Protocols

Peroxisomes of higher eukaryotes, glycosomes of kinetoplastids, & glyoxysomes of plants are related microbody organelles that perform differing metabolic functions tailored to their cellular environments. The close evolutionary relationship of these organelles is most clearly evidenced by the conservation of proteins involved in matrix protein import and biogenesis. glycosome can be viewed as an offshoot of the peroxisomal lineage with additional metabolic functions, specifically glycolysi - [Read Biogenesis and Function of Peroxisomes and Glycosomes]

Derivation of Trophoblast Stem (TS) Cell Lines from Blastocysts Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/18/pdb.prot4407

Category: Stem Cell Protocols

This protocol decribes derivation of TS cell lines from 3.5-days post coitum (dpc) mouse blastocysts. The procedure is similar to the derivation of embryonic stem (ES) cell lines. However, the success rate is considerably higher, and less expertise is required to recognize pluripotent TS cell colonies. - [Read Derivation of Trophoblast Stem (TS) Cell Lines from Blastocysts Protocol]

Fixing Attached Cells in Organic Solvents Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/21/pdb.prot4293

Category: Cell Culture Protocols: Cell Fixing Protocols

Organic solvents such as alcohols and acetone remove lipids and dehydrate cells, precipitating the proteins on the cellular architecture. Be aware that different antigens may be affected differently by the various solvents. If no previous data are available for your antigen, start with the 50/50 mixture. For tissue culture dishes, concentrations of acetone higher than 50% will destroy the integrity of the plastic. - [Read Fixing Attached Cells in Organic Solvents Protocol]

Fluorescent Dyes for Flow Cytometric Analysis - http://www.ebioscience.com/ebioscience/appls/Dyes.htm

Category: Cell Biology and Cell Culture: Flow Cytometry Protocols: Flow Cytometry Immunofluorescence Staining Protocols

Fluorescent dyes absorb light at certain wavelengths and in turn emit their fluorescence energy at a higher wavelength. Each dye has a distinct emission spectrum, which can be exploited for multicolor analysis. eBioscience antibodies are available conjugated to a wide variety of fluorochromes. - [Read Fluorescent Dyes for Flow Cytometric Analysis]

Live Imaging of Caenorhabditis elegans: Observation of Nematodes and Data Collection Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/29/pdb.ip18

Category: C. elegans Protocols

At low magnification, dissection microscopes are useful, whereas at higher magnification and resolution, a wide range of optical methods can be used, including differential interference contrast (DIC) optics, phase contrast, fluorescence, polarized light, confocal, and dark field. - [Read Live Imaging of Caenorhabditis elegans: Observation of Nematodes and Data Collection Protocol]

Rapid Elution of DNA Agarose Gels Protocol - http://www.fhcrc.org/science/labs/hahn/methods/mol_bio_meth/dna_spin_ext.html

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

Rapid Elution of DNA Agarose Gels Protocol. This method allows quick purification of DNA fragments from agarose gels for use in cloning and other reactions. Higher yields of purified DNA can be obtained from commercially available purification kits, however greater ligation efficiencies per given amount of DNA have been seen with the use of these described spin columns. Hahn Lab. - [Read Rapid Elution of DNA Agarose Gels Protocol]

Transient Transfection: Viral Production - http://genetics.med.harvard.edu/~cepko/protocol/mike/V1.html

Category: Transfection Protocols: Transient Transfection Protocols

This transient transfection protocol for the ecotropic/amphotropic producer line includes instructions for titering and concentration of viral stocks. This procedure gives consistently higher transfection efficiency. - [Read Transient Transfection: Viral Production]

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.

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.
