In this volume of Methods in Molecular Biology™, expert investigators offer comprehensive, complementary, and cutting-edge technologies for studies of gene regulation. The chapters of Gene Regulation: Methods and Protocols are organized to provide an integrated and a coherent view of control systems and their associated components. The protocols are broad in their scope. They include molecular, biochemical, spectroscopic techniques as well as high throughput strategies. Written in the highly successful Methods in Molecular Biology™ series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls.

Comprehensive and broad in their scope, the protocols are useful to researchers in many disciplines including molecular biology, genomics, biochemistry, biomedicine, nutrition, and agricultural sciences.

range, increase or decrease the output on the sonicator and the number of pulses or cycles during sonication. 6. After you have optimized the sonication conditions, determine the efficiency of HaloTag binding (Subheading 3.7) to ensure that the sonication conditions are optimal for HaloLink Resin capture. 3.7. Analysis of HaloTag Fusion Protein Binding Efficiency to HaloLink Resin This protocol requires the use of a fluorimager for detection of fluorescent bands within an SDS gel. If such

DNA. To obtain higher amounts of DNA, increase the number of HaloCHIP reactions performed, following the protocol as recommended, and pool purified DNA at the end of the process. This DNA can then be lyophilized to the desired concentration. 6. HaloLink resin will settle quite quickly in ethanol, therefore it is important to mix gently right before pipetting to obtain a uniform solution. 7. Excessive cross-linking can reduce the ability of the HaloTag protein to bind to its resin. If this is

determination of DNA concentration in small volumes. 6. Gel drier for drying short and long polyacrylamide gel. 3. Methods We have developed a strategy for the detection of protein binding regions in long (<10 kb) fragments of genomic DNA (Fig. 1) (12). With this strategy restriction fragments, containing transcription factor binding sites, derived from promoter region of any gene may be identified by combination of EMSA and denaturing PAGE. The following is a detailed description of the methods
