摘要:
The invention involves an apparatus useful in analysis of liquid samples. At least 3 zones are provided which contain reactants which interact with the analyte and each other, leading to the detection reaction. The apparatus also has a fluid application means for reception of a liquid, and a waste zone, which absorbs excess liquid after the detection reaction has taken place. The fluid application means and waste zone are positioned at opposite ends of the apparatus.
摘要:
An apparatus for determining an analyte in a sample, as well as a method for carrying this out, are disclosed. The apparatus utilizes a first zone containing a labeled substance, and a second zone which permits separation of a mobile detectable moiety from unreacted reaction component. Detectable moiety is the product of reaction between reaction component and labeled substance.

This invention relates to apparatus useful in determining a component or components of a test sample, as well as methods using these apparatus. Of particular interest are apparatus and methods which involve formation and determination of quarternary complexes.
摘要:
The invention relates to an assay for determining an analyte in a fluid sample. Three receptors are used, with formation of a quaternary or four member complex. One of the receptors is bound to a solid phase, and binds to complexes of another receptor and the analyte. A third receptor is labelled, and it, too, binds analyte. The invention also involves the use of a displacement solution to wash fluid sample from solid phase after the first portion of the quaternary complex forms, i.e., prior to binding with the labelled receptor.
