If you run ChIP assays (chromatin immunoprecipitation), consider trying the new Thermo Scientific Pierce Magnetic ChIP Kit. It provides a convenient method for efficient isolation of chromatin-bound DNA for subsequent quantitation by PCR.
Use the new Pierce Magnetic RNA-Protein Pull-Down Kit to end-label RNA with desthiobiotin and then enrich for target RNA-binding proteins. The complete kit contains sufficient reagents for 20 RNA labeling reactions and 20 protein-RNA pull-down assays.
