Abstract
Concentration of polyethylene glycol (PEG) has been measured satisfactorily using only 0.25 ml of intestinal aspirate (containing approximately 2.5 mg/l PEG). Hyden's turbidimetric assay was modified by reading turbidity at 420 mmu. The addition of extra protein was found to facilitate filtration after protein precipitation.
摘要
仅使用0.25毫升肠吸出物（含有约2.5毫克/升聚乙二醇（PEG））就已令人满意地测量出了聚乙二醇（PEG）的浓度。通过在420毫微米处读取吸光度对海登比浊法进行了改进。发现添加额外的蛋白质有助于蛋白质沉淀后的过滤。
