Analytical element for theophylline determination using buffer in a subbing zone |
| abstract |
Theophylline can be determined with an analytical element and method which utilize the inhibition, by theophylline, of alkaline phosphatase activity on an appropriate substrate. The assay is carried out at a pH of 9 or less. The element comprises a porous spreading zone, a subbing zone and at least one other zone. The zones are in fluid contact with each other. The isoenzyme of alkaline phosphatase and a suitable substrate for the isoenzyme are located in different zones of the element. The subbing zone contains polyvinylpyrrolidone and a buffer for maintaining a pH of 9 or less. |
