Direct Retrieval of DNA Fragments from Pulsed-field Gels Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4083

Category: Nucleic Acid Electrophoresis Protocols: Pulsed Field Gel Electrophoresis Protocols

Protocol for direct retrieval of DNA fragments from pulsed-field gels. A gel slice containing a fragment of DNA resolved by pulsed-field gel electrophoresis is treated with agarase. The released DNA can be used as a substrate for ligation or restriction without further purification. - [Read Direct Retrieval of DNA Fragments from Pulsed-field Gels Protocol]

Fractionation of Maize Embryo Proteins for 2-D Gel Electrophoresis Using Multicompartment Electrolyz - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4235

Category: Plant Biology Protocols: Plant Proteins, Peptides and Antigens

Protocol describes a method for performing isoelectric fractionation of a maize embryo sample using a multicompartment electrolyzer(MCE). This prefractionation of proteins having pIs within a certain pH interval is essential for allowing high loads of protein to be resolved on narrow and ultra-narrow immobilized pH gradients used in 2D electrophoresis. The isoelectric membranes in the MCE act like isoelectric traps capturing all the protein species having pIs encompassing the pI value of each... - [Read Fractionation of Maize Embryo Proteins for 2-D Gel Electrophoresis Using Multicompartment Electrolyz]

Pulsed-field Gel Electrophoresis via Contour-clamped Homogeneous Electric Field Gels Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4033

Category: Nucleic Acid Electrophoresis Protocols: Pulsed Field Gel Electrophoresis Protocols

Protocol for pulsed-field gel electrophoresis via contour-clamped homogeneous electric field gels. In CHEF gels, the electric field is generated from multiple electrodes, arranged in a square of hexagonal contour around the horizontal gel and clamped to predetermined potentials. Using a combination of low field strengths, low concentrations of aragose, long switching intervals, and extended periods of electrophoresis, DNAs up to 5000 kb can be resolved. - [Read Pulsed-field Gel Electrophoresis via Contour-clamped Homogeneous Electric Field Gels Protocol]

Single-Strand Conformation Polymorphism Analysis Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/14/pdb.prot4118

Category: Genetics and Genomics: Cancer Genetics Protocols: Single Strand Conformational Polymorphism(SSCP) Protocols

Single-strand confirmation polymorphism analysis (SSCP) is a powerful and robust method for the detection of DNA sequence changes (single-base substitutions) based on shifts in electrophoretic mobility. In this protocol, the target sequence is simultaneously labeled and amplified, then heat-denatured and resolved by non-denaturing polyacrylamide gel electrophoresis. - [Read Single-Strand Conformation Polymorphism Analysis Protocol]

Single-Strand Conformation Polymorphism Analysis Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/14/pdb.prot4118

Category: DNA Protein Interactions Protocols: Electrophoretic Mobility Shift Assays EMSA Protocols

The target sequence is simultaneously labeled and amplified, then heat-denatured and resolved by non-denaturing polyacrylamide gel electrophoresis. Differences in sequence alter the conformation of the DNA and hence its electrophoretic mobility and, because of the high resolution of polyacrylamide gels, most conformational changes caused by subtle changes in sequence can be detected. - [Read Single-Strand Conformation Polymorphism Analysis Protocol]
