摘要

Abstract

Objective,2,To study the application of a new detection method of residual protein.,Methods,2,The detection range and anti-interference detection ability of the new residual protein monitoring method were tested and the data was compared with the UV-Vis OPA method. The influence of the differences among five different types of protein on the two detection results and the detection rate of residual protein in different devices were tested.,Results,2,The new residual protein detection method's detection limit was 0.1μg/mL, and it was insensitive to non-oxidizing interferents. The difference in protein is low, and the Cv value is 13.74. The detection rate of protein was better than that of UV-Vis OPA method, and the difference was significant (P > 0.01).,Conclusion,2,Compared with UV-vis OPA method, the new detection method of residual protein has higher sensitivity, a more comprehensive detection range, and a lower difference between proteins. It is effective to monitor the residual protein in device cleaning, and it is worth popularizing.
