| Popis: | 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. |
