Protocol for detection of autoantibodies with self-assembling radiolabeled antigen tetramers. Details how to produce radiolabeled antigen-streptavidin tetramers for detection of antibodies by immunoprecipitation. Optionally, the antigen tetramers can be denatured to compare responses to folded and unfolded antigen in the same system. This technique can be applied to a large or small number of samples, and a given sample can be simultaneously assayed with multiple antigens. - [Read Detection of Autoantibodies with Self-Assembling Radiolabeled Antigen Tetramers 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]

Immunoblotting: Preparing Immunoprecipitated Proteins Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/21/pdb.prot4300

Category: Western Blot Protocols

Protein immunoprecipitation can be a useful preparative step for immunoblotting. For very rare proteins, the protein of interest can be purified and concentrated by standard immunoprecipitation techniques before immunoblotting. In addition, protein-protein interactions can be tested with an immunoprecipitating antibody that is specific for one protein of a complex and an immunoblotting antibody that is specific for a second member of the complex. - [Read Immunoblotting: Preparing Immunoprecipitated Proteins Protocol]

Immunoprecipitation of mRNA-Protein Complexes Protocol - http://www.nature.com/nprot/journal/v1/n2/pdf/nprot.2006.82.pdf

Category: Immunology: Immunoprecipitation Protocols

Protocol for immunoprecipitation of mRNA-protein complexes. In this protocol, an antibody targeting an RBP of interest is used to immunoprecipitate the RBP and any interacting molecules from a cell lysate. Reverse transcription followed by PCR is then used to identify individual mRNAs isolated with the RBP. This method focuses on examining an association between a specific RBP-mRNA complex, and it is best suited for a small scale screening of known or putative binding partners. - [Read Immunoprecipitation of mRNA-Protein Complexes Protocol]

Immunoprecipitation: Denaturing Lysis Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4534

Category: Immunology: Immunoprecipitation Protocols

For many sources of antigens, one useful method of lysis is to treat cells with harsh, denaturing solutions to release most of the protein antigens, as described here. The lysates are then diluted to reduce the denaturing conditions to levels that are suitable for the formation of antibody-antigen complexes. The resulting solution is precleared prior to immunoprecipitation. - [Read Immunoprecipitation: Denaturing Lysis Protocol]

Immunoprecipitation: Lysing Bacteria by Sonication Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4532

Category: Bacterial Cell Culture Protocols

In this protocol, bacterial cells are lysed by being subjected to short, intense treatments with ultrasound, which breaks the cell walls and shears the DNA into sizes that will not affect the viscosity of the samples. Note that this method causes some denaturation of the samples. The resulting lysate is ready for preclearing. - [Read Immunoprecipitation: Lysing Bacteria by Sonication Protocol]

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]

In Vitro Translated Xenopus Mos Kinase Assay Protocol

In Vitro Translated Xenopus Mos Kinase Assay Protocol. In response to progesterone, immature Xenopus oocytes mature to eggs that can be fertilized. The Mos protein kinase is essential for oocyte maturation, most likely due to its ability to activate the MAP kinase cascade. This MAP kinase cascade eventually leads to the activation of Cdc2/cyclin B and entry into M phase. In this protocol, tagged Mos kinase is translated in vitro, immunopurified, and used in a kinase assay.
