Abstract
Disclosed is an improved method for the detection of an analyte in a fluid test sample using a strip of a negatively charged matrix material having a zone containing mobile, labeled binding partner for the analyte and a separate zone for capturing the labeled binding partner as it is carried through this zone by the fluid test sample. The improvement involves combining the fluid test sample with a polyalkoxylated amine surfactant to control non-specific binding of the labeled binding partner to the negatively charged matrix material.
