Abstract

Effect of six organic solvents—methanol, ethanol, propanol, dimethyl sulphoxide (DMSO), N,N-dimethyl formamide (DMF), and glycerol on the conformation and interaction of catalase and anticatalase antibodies were studied with the aim of identifying the solvents in which antigen–antibody interactions are strong. The antigen binding activity of the antibodies in the various organic solvents increased in the following order: ethanol < methanol < no organic solvent < propanol < DMSO < DMF < glycerol. The structure of both the antibody and the antigen molecule was affected significantly in 40% concentration of the organic solvents used in this study. Catalase activity was inhibited in DMSO. However, the enzyme was activated in DMF upto about 50% of its concentration.
