Method for the removal of interfering substances, including caffeine, in theophylline assays |
摘要 |
A method for the separation of theophylline and caffeine contained in body fluids is provided. A macroreticular styrene-divinylbenzene copolymer resin activated by a protic solvent is utilized. The body fluid is eluted with water in an isocratic manner to afford a theophylline sample uncontaminated with caffeine. Such samples are useful in immunoassay procedures for the measurement of theophylline.
