Members of the ISWI family of chromatin remodeling factors hydrolyze ATP to reposition nucleosomes along DNA. Here we show that the yeast Isw2 complex interacts with DNA in a nucleotide-dependent manner at physiological ionic strength. Isw2 efficiently binds DNA in the absence of nucleotides and in the presence of a nonhydrolyzable ATP analog. Conversely,(More)
Cross-reactions with metabolites are an ever-recurring problem encountered in the use of radioimmunoassay techniques to determine active compounds in biological material. Metabolites may interfere with the assay of the parent drug to a variable extent. Taking 8-chloro-11-(4-methyl-1-piperazinyl)-5H-dibenzo[b,e][1,4]diazepine (clozapine as an example, it was(More)
An improved method for deconvoluting energy-resolved collision-induced dissociation cross sections yields ligand binding energies for organometallic complexes with substantially less prior information than before. Application to isomeric 2:1 complexes of azabox ligands with Cu(I) gives consistent results for the binding energies of the ligands to homo- and(More)
