Modification of polyethylene glycol estimation suitable for use with small mammals.
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.
