Category: Nucleic Acid Purification Protocols: DNA Isolation Protocols: Genomic DNA Isolation Protocols

In this protocol, the DNA-binding capacity of Wizard MagneSil particles is used to capture and release a consistent amount of DNA (100 ng) across a wide range of samples.  At the end of the procedure, the DNA is eluted into 100 µl Elution Buffer to give a final concentration of 1 ng/µl, relieving the need for postpurification DNA quantitation. - [Read DNA IQ Isolation of Genomic DNA from Stains and Buccal Swabs Protocol]

Category: Chromatography Protocols: Dye Ligand Affinity Chromatography Protocols

Protocol for the optimization of elution condition for dye-ligand affinity chromotography. Elution methods used in dye-ligand affinity chromatography may be either selective or nonselective in nature.  Usually, selective elution methods are applied in combination with group-specific adsorbents, such as dye-ligand adsorbents, and nonselective elution methods are used in combination with highly specific adsorbents. - [Read Optimization of Elution Conditions for Dye-Ligand Affinity Chromatography Protocol]

Category: Chromatography Protocols: Affinity Chromatography Protocols

Recombinant proteins, constructed in pGEX vectors, are fused to glutathione S-transferase (GST) and can be purified to near homogeneity by affinity chromatography on glutathione-agarose.  Bound GST-fusion proteins are readily displaced from the column by elution with buffers containing free glutathione. - [Read Purification of Fusion Proteins by Affinity Chromatography on Glutathione Agarose Protocol]

Category: Chromatography Protocols: Immobilized Metal Ion Affinity Chromatography Protocols

Immobilized metal-ion affinity chromatography (IMAC) is suitable for the purification of proteins under denaturing conditions.  Either guanidine-HCl or urea can be used, although guanidine-HCl is a stronger denaturant than urea.  Proteins that have been adsorbed to the column in the presence of guanidine-binding buffer may be washed with urea-binding buffer and eluted with urea elution buffer. - [Read Purification of Histidine-Tagged Proteins under Denaturing Conditions Using IMAC Protocol]

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.

Category: Immunology: Immunoprecipitation Protocols

Protocol for RNA co-immunopurification with specific RNA-binding proteins. Includes: Binding to IgG beads; Washing the beads; Elution with TEV-protease; RNA isolation. - [Read RNA co-immunopurification with specific RNA-binding proteins]

Category: Chromatography Protocols: DNA RNA Affinity Chromatography

Chromatography on oligo(dT) columns is the preferred method for large-scale purification (>25 µg) of poly(A)+ RNA extracted from mammalian cells. Typically, between 1% and 10% of the RNA applied to the oligo(dT) column is recovered as poly(A)+ RNA. Because the method can be frustratingly slow, it is not recommended for purification of poly(A)+ RNA from multiple samples. For this purpose, batch elution (Selection of Poly(A)+ RNA by Batch Chromatography) is the better choice. - [Read Selection of Poly(A)+ RNA by Oligo(dT)-Cellulose Chromatography - Subscription Required]
