Influence of Mannitol on Determination of the Content of Polypeptide in Lyophilized Thymosin for Injection by Lowry Method
Xu Ying;Cheng Yi(Lanzhou Institute of Biological Products,Lanzhou 730046)
When the contents of polypeptide in lyophilized thymosin for injection are determined by Lowry method, the result shows that is obviously increased (p0.0005) since it is added mannitol before the freeze drying. This paper confirms that the equivalent quantity of mannitol controlled with the one of the samples can eliminate the interference.
