Ultrafiltration for improved assay of urinary enzymes
Clinical Chemistry
|January 1, 1977
Abstract:
Ultrafiltration of urine and rapidly separates urinary enzymes from inhibitors, activators, and heat-stable, spurious activities present in urine. Using eight enzymes of clinical interest as examples, we verified the reliability of results obtained after ultrafiltration by comparsion with results obtained after gel filtration.
