The present invention provides a device and a process for detecting an analyte in a biological fluid. The device comprises a separating matrix for separating analyte from the fluid and means for detecting the analyte where the separating matrix contains HEPES buffer preferably in an amount, between 70 and 150 millimolar. The process comprises applying the sample to the device having a separating matrix and then detecting analyte in the sample using the detection means. The presence of HEPES in the separation layer shortened the detection time.

Why it's free to use
- Filed June 30, 1994 and granted July 14, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 30, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 30, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
