Assay of Cyclic AMP in Lysates of Cells - http://www.signaling-gateway.org/data/cgi-bin/ProtocolFile.cgi/afcs_PP00000015.pdf?pid=PP00000015

Category: Signalling Signal Transduction Protocols

Protocol allows you to measure the content of cyclic adenosine 3',5'-monophosphate (cyclic AMP or cAMP) in splenic B lymphocytes (B cells) in an enzyme-linked immunoassay. This protocol utilizes acetylation of cAMP to improve sensitivity and reduce interference. Protocol includes information on: how to determine cAMP, calculations and reagents and materials. - [Read Assay of Cyclic AMP in Lysates of Cells]

FAQs About Cell Sorting - http://cyto.mednet.ucla.edu/Protocols/question.htm

Category: Cell Biology and Cell Culture: Flow Cytometry Protocols: Cell Sorting Protocols

Questions and answers about cell sorting. Includes: When should I use fluorescence activated cell sorting over bulk separation methods like panning or magnetic bead separations? Will my cells be harmed by the sorting process? How many cells do I need to prepare to recover 1 X 106 of a population that comprises 10% of the cells? Are there ways to improve sort recovery? etc... - [Read FAQs About Cell Sorting]

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]

Injection of dsRNA and Electroporation in Avian Embryos Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4504

Category: RNAi Technology Protocols: RNAi Avian Embryos Protocols

Protocol describes a method for in ovo transfection of avian embryos with double-stranded RNA (dsRNA). The dsRNA is injected into the spinal cord of the embryo. Subsequent electroporation facilitates the cellular uptake of the dsRNA molecules. It may be necessary to optimize the stage of the embryo and the electroporation procedure to improve the effectiveness of in ovo RNAi—cell competence changes with differentiation. - [Read Injection of dsRNA and Electroporation in Avian Embryos Protocol]

Phosphatase Treatment of Linearized Vector Protocol - http://openwetware.org/wiki/Phosphatase_treatment_of_linearized_vector

Category: Cloning Protocols: Vector Protocols

To minimize self-ligated vector in your transformation, treat your linearized vector with a phosphatase to remove the 5' phosphates necessary for ligation. This should improve the percentage of colonies with inserts. - [Read Phosphatase Treatment of Linearized Vector Protocol]

Preparation of Arabidopsis Chloroplasts Protocol - http://www.cshprotocols.org/cgi/content/abstract/2007/1/pdb.prot4681

Category: Plant Biology Protocols: Arabidopsis Tissue Culture

It is desirable to prepare subcellular fractions, either to localize proteins or to improve the sensitivity of protein detection. This procedure describes the enrichment of chloroplasts from Arabidopsis. - [Read Preparation of Arabidopsis Chloroplasts Protocol]

Preparation of Arabidopsis Mitochondria Protocol - http://www.cshprotocols.org/cgi/content/abstract/2007/1/pdb.prot4682

Category: Plant Biology Protocols: Arabidopsis Tissue Culture

It is often desirable to prepare subcellular fractions, either to localize proteins or to improve the sensitivity of protein detection. This procedure describes the enrichment of mitochondria from Arabidopsis. - [Read Preparation of Arabidopsis Mitochondria Protocol]

Slide Preparation for Cytogenetics Protocol - http://info.med.yale.edu/genetics/ward/tavi/Cytom-slideprep.html

Category: Cytogenetics Protocols

Protocol for slide preparation for cytogenetics. Includes: Improved cell recovery by microcentrifugation; Slide storage; "Controlled" chromosome spreading; Dropping cells from a height does not improve spreading; GTG-banding. - [Read Slide Preparation for Cytogenetics Protocol]
