Technology
A technique that utilizes immunoprecipitation to find protein-DNA interactions in a biological sample. First, the sample is treated causing the formation of protein-chromatin crosslinks. Then, the sample is sheared to separate individual protein-DNA complexes. Finally, an antibody directed against a protein of interest is applied and the protein-DNA complexes are immunoprecipitated.
Technology
A type of ELISA assay that uses a reference antigen to competitively bind labeled antibody against an antigen of interest. The strength of the signal interference caused by antibody bound to the reference antigen is used to determine the concentration of the antigen of interest.
