Objective.
To quantitatively assess the influence of reducing agents on biological macromolecules and on the possible repair of oxidative damage.
Methods.
Samples (antibody, enzyme, DNA, and diluted serum) were treated with reducing agents (ammonium ferrous sulfate, ascorbic acid, potassium iodide, and sodium hyposulfite) in the experimental group and with NaCl in the control group.
Enzyme-linked immunosorbent assay and quantitative PCR were used to determine the activity of antibody, enzyme, and DNA.
Native gel electrophoresis (Native-PAGE) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) were used to determine protein structure.
Reducing agents that had no inhibitory effect on biological macromolecules were selected.
Antibodies were treated with oxidants to caused oxidative damage and then treated with reducing agents, and the possible repair of oxidative damage was assessed.
Results.
Certain concentrations of ammonium ferrous sulfate resulted in significant inhibition of antibody, enzyme, DNA, and diluted serum.
Certain concentrations of ascorbic acid resulted in significant inhibition of antibody.
Sodium hyposulfite and potassium iodide had no effect on antibody, enzyme, DNA, and diluted serum.
The OD values in group A (in which HBsAb was treated by oxidation and then a reductant) were significantly higher than those in group B (HBsAb treated by oxidation).
Conclusion.
Ammonium ferrous sulfate, ascorbic acid, sodium hyposulfite, and potassium iodide had different effects on antibody, enzyme, DNA, and diluted serum.
The reduction in antibody activity due to an oxidant was partially repaired by a reductant.
