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.
研究了六种有机溶剂——甲醇、乙醇、丙醇、二甲基亚砜(DMSO)、N,N-二甲基甲酰胺(DMF)和甘油对过氧化氢酶和抗过氧化氢酶抗体的构象及相互作用的影响,目的是确定抗原-抗体相互作用较强的溶剂。抗体在各种有机溶剂中的抗原结合活性按以下顺序增加:乙醇<甲醇<无有机溶剂<丙醇<DMSO<DMF<甘油。在本研究使用的40%浓度的有机溶剂中,抗体和抗原分子的结构均受到显著影响。过氧化氢酶活性在DMSO中受到抑制。然而,该酶在DMF中被激活,其浓度可达约50%。
