OBJECTIVE: To establish a method for the content determination of protein in Sabin IPV.
METHODS: Using lowry method combined with being precipitated by trichloroacetic acid to determine the content of protein in Sabin IPV. Changing different conditions to optimize the experiment to establish a improved lowry method. And the sample recovery test was also conducted.
RESULTS: The method can exclude the interference of free aminoacid, phenols and some other additives. The calibration curve was in good linearity of protein within the range of 2.5 microg/ml-40 Microg/ml, r = 0.9998. Under the best conditions, the mean recovery was 95.32%, the CV in a batch and between batches were both < 10%.
CONCLUSION: The method can be used to determine the micro content of protein in vaccines.
