Protocol describes how to identify cloned cDNAs encoding proteins that bind to specific DNA sequences. The methods used are very similar to those used for immunological screening of expression libraries except that the nitrocellulose filters carrying immobilized proteins are screened with 32P-labeled double-stranded DNA rather than with antibodies. - [Read Identifying DNA-binding Proteins in Bacteriophage ambda Expression Libraries Protocol]

Category: Reporter Gene Assays: GFP Assay Protocols

Specific molecular components can be efficiently labeled by a combination of three methods: chemical transfection of GFP-fusion constructs, staining of chromosomes with the DNA-specific, fluorescent dye Hoechst 33342, and microinjection of fluorescently conjugated proteins. This procedure provides an example of using all three methods in sequence to label components of living HeLa cells. These methods should be followed in the order presented, but any of them can be omitted when not needed. - [Read Imaging Hoechst-Labeled Chromosomes and Fluorescent Proteins during the Cell Cycle]

Category: Western Blot Protocols: Antigen Detection Methods Protocols

The blot is blocked to prevent nonspecific adsorption of the immunological reagents.  Antibodies are then bound to the proteins immobilized on the membrane, and the antigen is detected by labeling the antibodies with conveniently identified tags.  Common labeling methods for chemiluminescent detection include anti-immunoglobulin antibody-coupled enzymes such as horseradish peroxidase, which catalyzes the oxidation of luminol and in turn releases light. - [Read Immunoblotting: Antigen Detection Using Chemiluminescence Protocol]

Category: Immunohistochemistry Protocols

Describes two methods for using the immunoperoxidase reaction to localize antigens at the electron microscope level; one for adherent cultured cells and one for tissue sections. The reaction conditions are first optimized at the light microscope level and then adapted for EM level observation. These methods allow for reliable detection of antigens at the cell surface, within the cell, and especially in membrane bounded organelles. - [Read Immunoperoxidase Methods for Localization of Antigens in Cultured Cells and Tissues]

To accurately predict the activity of a transgene it is critical to understand its location and dynamics in the 3-D interphase nucleus. Developed in situ methods to visualize transgenes (including single copy genes) & their transcripts during interphase from different tissues & plant species. These techniques reduce the time necessary for characterization of transgene integration by eliminating the need for time-consuming segregation analysis and extend characterization to the interphase nucleus - [Read In Situ Methods to Localize Transgenes and Transcripts in Interphase Nuclei]

Describes generating CTL against some commonly used target antigens. Two methods for the quantitation of CTL activity are described based on the two pathways used bt CTL to kill target cells. In one pathway, they release lytic granules containing perforin and granzymes, leading to apoptosis and target cell lysis. In a second pathway, they trigger apoptosis via Fas/Fas ligand interactions. - [Read Induction and Measurement of Cytotoxic T Lymphocyte Activity Protocol]
