Description
Product Description of BABEs
Bromoacetamidobenzyl-EDTA (BABE) is a chelate labeling reagent that conjugates with sulfhydryl groups. The iron chelate of BABE (FeBABE) is a unique tool for determining the three-dimensional structure of proteins and the binding structures of protein-protein or protein-DNA complexes. BABE adds EDTA moieties to proteins through their sulfhydryl groups. Once attached to a protein, FeBABE cuts a nearby peptide or DNA chain. The cleavage site is within 12 angstroms of the FeBABE binding site. Iron (II)-chelate cleaves a peptide or DNA chain in the presence of hydrogen peroxide. The cleavage reaction completes quickly: 10 seconds to 20 minutes of incubation is sufficient. The size of the cleaved fragment is analyzed with gel electrophoresis such as SDS-PAGE.
