Abstract
An emulsion (in which an aqueous medium contains small liquid droplets coated with a protein that will interact specifically with a select protein) is mixed with a liquid sample, time is allowed for interaction to occur and the mixture is then exposed to a tagged antibody specific to the select protein. After an appropriate hold time the emulsion is broken and the protein that previously covered the disperse droplets becomes concentrated at the surface. The surface is checked for the presence of the tagged antibodies to establish the presence of absence of the select protein.
