A collaborative study to determine the suitability of establishing an Author's Preparation of dextran sulfate as an international standard has been carried out. It was concluded from the results that the existing Author's Preparation should not be used for this purpose. The factors governing this decision were (a) that only a small amount of the preparation is now available, and (b) that the amount of material in the ampoules is not as accurately known as is desirable for an international standard owing to the degree of hydration of the original material.The International Unit of Dextran Sulfate has been defined as the activity contained in 0.04 mg of the Author's Preparation.
开展了一项合作研究，以确定将作者的硫酸葡聚糖制剂确立为国际标准的适用性。根据研究结果得出结论，现有的作者制剂不应用于此目的。做出这一决定的因素包括：（a）目前该制剂的可用量很少；（b）由于原始材料的水合程度，安瓿中材料的量不像国际标准所要求的那样精确已知。硫酸葡聚糖的国际单位已定义为0.04毫克作者制剂中所含的活性。
