Abstract

To investigate the target-specificity and biological activity of Streptococcus serum antibody and sulfate amikacin conjugates. The recent used polyethylene glycol 6000 (PEG6000) as the coupling agent to produce Coupled complexes of Streptococcus serum antibody and sulfate amikacin. Then, analyzed the antibody being in conjugates specificity which against Streptococcus, and the antibody being in conjugates immunogenicity. Besides, we also detected the acute toxicity, antimicrobial activity and bioavailability of sulfate amikacin being in conjugates. As a result, the antibody specific binding to Streptococcus, instead of Escherichia coil, Pasteurella and Staphylococcus aureus. Biological activity results showed that coupling decreased Streptococcus serum antibody immunogenicity, increased Streptococcus serum antibody response sensitivity. Simultaneously, the results indicated that coupling reduced the acute toxicity of sulfate amikacin, improved sulfate amikacin bioavailability and antimicrobial activity of sulfate amikacin. The combination effect on the antibacterial activity of drug and the biological activity of serum antibody is helpful for the practical application of targeted drugs.
