ANTIBODY PURIFICATION by affinity chromatography. By Beth, Mullins Lab UCSF. To affinity purify antibodies, generate lots of E. coli lysate that contains your antigen. If the protein can stand freeze thawing, then go ahead and purify the protein from e. coli lysate and keep it frozen until you need to couple it to a CH-sepharose column. - [Read ANTIBODY PURIFICATION by affinity chromatography]

Category: Immunology: Immunoprecipitation Protocols: Chromatin Immunoprecipitation Protocols

Genome-wide location analysis, also known as ChIP-Chip, combines chromatin immunoprecipitation and DNA microarray analysis to identify protein-DNA interactions that occur in living cells. Protein-DNA interactions are captured in vivo by chemical crosslinking. Cell lysis, DNA fragmentation and immunoaffinity purification of the desired protein will co-purify DNA fragments that are associated with that protein. - [Read Chromatin Immunoprecipitation and Microarray-Based Analysis of Protein Location Protocol]

Category: Immunology: Immunoprecipitation Protocols

Protocols for detection and purification of proteins tagged with a particular epitope, the FLAG tag, although the same general approach can be applied to other epitope tags. The protocols employ the anti-FLAG M2 antibody to detect and purify FLAG-tagged proteins. The methods presented are immunoprecipitation of FLAG fusion proteins from cells using an anti-FLAG M2 affinity gel, detection of FLAG fusion proteins by western blotting, and purification of FLAG fusion proteins by anti-FLAG. - [Read Epitope Tagging of Recombinant Proteins Protocol]
