OBJECTIVE To establish a gel filtration chromatography (GFC) for determination of conjugation rate and yield of intermediate; conjugation rate was increased through optimation experiment. METHODS In order to increase output,the material ratio for the reaction, pH, temperature and reaction time were adjusted, GFC was applied to quantitative analysis, mobile phase was 0.02 mol·L -1 pH 6.8 dihydogenphosphate solution with a flow rate of 0.5 mL·min -1, the UV detection wavelength was 280 nm. RESULTS The conjugation rate increased from 10.19% to 13.48%. CONCLUSION The established method is simple,rapid, sensitive and accurate for optimizing experimental condition and increasing the conjugation rate.
