Category: Mouse Protocols: Assembling Chimeras Mouse Protocols

Protocol describes a method for assembling aggregates between ES cells and diploid embryos. The resulting chimeras are useful for separating certain extraembryonic phenotypes from phenotypes in the embryo proper, since the diploid embryo contributes to all parts of the conceptus, but the ES cell component does not contribute to the trophoblast or yolk sac endoderm. - [Read Assembling Aggregates between Embryonic Stem (ES) Cells and Diploid Embryos Protocol]

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

Bradford Protein Assay Spectrophotometry.  Includes spectrophotometry information and the Bradford protein assay: A spectrophotometer or colorimeter makes use of the transmission of light through a solution to determine the concentration of a solute within the solution.  A spectrophtometer differs from a colorimeter in the manner in which light is separated into its component wavelengths.  A spectrophotometer uses a prism to separate light and a colorimeter uses filters. - [Read Bradford Protein Assay Spectrophotometry]

Category: Epigenetics and Methylation Protocols: ChIP Chromatin Immunoprecipitation Protocols

Chromatin Immunoprecipitation Protocol for Histone Modification Chromatin and Associated Proteins. Roderick O’Sullivan & Joost Martens. Chromatin Immunoprecipitation (ChIP) experiments are routinely performed in many laboratories around the world to examine the occupancy of proteins or chromatin modifications over particular stretches of the genome. - [Read Chromatin Immunoprecipitation Protocol for Histone Modification Chromatin and Associated Proteins]

Chromatin immunoprecipitation protocol to analyze histone modifications in Arabidopsis thaliana. Werner Aufsatz, Matzke Lab. Gregor Mendel Institute of Molecular Plant Biology, Austria. Includes Chromatin Crosslinking, Chromatin preparation, Pre-clearing and immuno precipitation (IP), Collection,washes and elution of immune complexes, Reverse crosslinking and DNA cleanup - [Read Chromatin immunoprecipitation protocol to analyze histone modifications in Arabidopsis thaliana]

Category: Chromatography Protocols: Liquid Chromatography Protocols

Protocol for configuration, column construction, and column packing for a capillary liquid chromatography system. Protocol describes a procedure for adapting conventional HPLC systems to provide accurate low-flow rates (0.4-4 µl/min) and gradients required to operate slurry-packed capillary columns.  A key component of this system is a commercial axial-beam longitudinal flow cell that can be fitted to several commercial UV detectors. - [Read Configuration Column Construction Column Packing for Capillary Liquid Chromatography]

Category: Plant Biology Protocols: Plant DNA RNA Isolation Protocols

Retroelements and their derivatives are a ubiquitous and abundant component of plant genomes. Major classes of retroelements include the Pseudoviridae (Ty1-copia ), the Metaviridae (Ty3 -gypsy) and the Retroposineae LINE (non-LTR) groups. All reverse transcribing elements can be included in a universal classification. Includes: Pseudoviridae (Ty1-copia) Degenerate Primers; Metaviridae (Ty3-gypsy) Element Degenerate Primers; LINE Element Degenerate Primers; PCR Programmes. - [Read Isolation of Retroelement from Plant Genomic DNA]

Category: Cell Biology and Cell Culture: Cell Culture Growth Media: Mammalian Cell Culture Growth Media Protocols

The culture medium is an essential component of the in vitro environment and must be selected or designed with care. This protocol provides guidelines for design of serum-containing and serum-free media, selective and specialty media, and media for growth under special conditions such as soft-agar growth. - [Read Media for Culture of Mammalian Cells Protocol]

Protocol describes a procedure for adapting conventional HPLC systems to provide accurate low-flow rates (0.4-4 µl/min) and gradients required to operate slurry-packed capillary columns.  A key component of this system is a commercial axial-beam longitudinal flow cell that can be fitted to a number of commercial UV detectors. - [Read Packing Capillary Columns for RP-HPLC Protocol]

Category: Plant Biology Protocols: Photosynthesis and Respiration Protocols

The physiological reactions of mitochondria and chloroplasts can be reduced to a series of electron transfers, catalyzed by specific enzymes found within the organelles. Thus, we can study the component processes of photosynthesis and respiration by isolating the organelles and measuring specific enzyme activity associated with that organelle. - [Read Photosynthesis and Respiration - Introduction]
