Studies on the Production of Purified Protein Derivative Tuberculins
Purified Protein Derivative Tuberculin의 생산시험
Abstract
For the establishment of more reliable and applicable methods for the diagnosis of tuberculosis in dairy cattle, avian- and mammalian PPD tuberculins were prepared according to the methods of Weybridge purified protein derivative tuberculins with minor modifications. PPD tuberculin was not only a very pure product from a chemical standpoint, but also one which, judged on the basis of laboratory results, was likely to be more potent and reliable than HCSM tuberculin.
