Cloning PCR Products into T Vectors Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot3834

Category: PCR Protocols: PCR Cloning Protocols

This method of direct cloning takes advantage of the unpaired adenosyl residue added to the 3' terminus of amplified DNAs by Taq and other thermostable polymerases. - [Read Cloning PCR Products into T Vectors Protocol]

Generation of Sets of Nested Deletion Mutants with Exonuclease III Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4078

Category: Genetics and Genomics: Genotyping Protocols: Mutation Detection Protocols

The double-stranded DNA of recombinant plasmid, phagemid, or bacteriophage M13 replicative form DNA is digested with two restriction enzymes whose sites of cleavage both lie between one end of the target DNA and the binding site for universal primer. The enzyme that cleaves nearer the target sequence must generate either a blunt end or a recessed 3' terminus; the other enzyme must generate a four-nucleotide protruding 3' terminus. - [Read Generation of Sets of Nested Deletion Mutants with Exonuclease III Protocol]

His Tag Nickel Affinity Chromatography Protocol PDF - http://www.mnstate.edu/provost/His_TagNiChromatogProtocol.pdf

Category: Chromatography Protocols

His Tag Nickel Affinity Chromatography Protocol PDF. The Wallert and Provost Lab. Theory and Introduction: Ni-Affinity Chromatography uses the ability of His to bind nickel. Six histadine amino acids at the end of a protein (either N or C terminus) is known as a 6X His tag. Nickel is bound to an agarose bead by chelation using nitroloacetic acid (NTA) beads. Several companies produce these beads as His Tagged proteins are some of the most used affinity tags in todayâ€™s market. - [Read His Tag Nickel Affinity Chromatography Protocol PDF]

Purification of Histidine-tagged Proteins by Immobilized Ni2+ Absorption Chromatography Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4088

Category: Chromatography Protocols: Affinity Chromatography Protocols

Recombinant proteins engineered to have a polyhistidine tail at either the carboxyl or amino terminus can easily be purified in one step by affinity chromatography on a resin carrying chelated nickel ions. Chromatography can be carried out in column or batch formats. After unbound proteins are washed away, the target protein is eluted using imidazole, which typically preserves the antigenic and functional features of the protein. - [Read Purification of Histidine-tagged Proteins by Immobilized Ni2+ Absorption Chromatography Protocol]
