| 摘要 |
A dry chemistry reagent system for detecting an analyte in a heterogenous fluid sample, said system comprising a bibulous membrane (3) of essentially uniform composition and a porosity gradient from one planar surface (2) thereof to the other (4), wherein said membrane's inherent fluid absorption and distribution characteristics have been modified by imbibing a conditioning agent, an indicator, flow control agent and reagent cocktail into its matrix, the effect of such absorption being to effect an essentially uniform distribution of indicator, flow control agent and reagent cocktail within the bibulous membrane thereby enhancing the uniformity of internal structure of the membrane so as to enhance the uniformity of absorption and modulate the rate of absorption of the fluid sample and its interaction with the reagent cocktail. Also a test kit containing the reagent system and a method for preparing the reagent system. |
