Description_x000D_ Packaging_x000D_ 1, 5 g in poly bottle_x000D_ Application_x000D_ For cleavage of tryptophanyl peptide bonds._x000D_ Biochem/physiol Actions_x000D_ 2-Iodosobenzoic acid (IBA) may be used to study enzyme structure and activity. IBA is used as an oxidant which oxidizes vicinal sulfhydryls to disulfides (cysteine residues) within enzymes leading to their inactivation or conformational changes. IBA is also used to cleave tryptophanyl peptide bonds.
