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.

5858382 - Method and pharmaceutical compositions for drug targeting - Owned by Yissum, Research Development Company of the Hebrew University of Jerusalem (Jerusalem)

A pharmaceutical composition comprising an oil/water emulsion wherein the oil droplets contain a drug in dissolved or dispersed or solubilized form. The droplets are further coated with adsorbed native or modified antibodies which provide targeting of the droplets and the drug. The process for preparing this composition comprises the steps of (i) dissolving or dispersing a drug in an oil phase, (ii) preparing an oil/water emulsion, (iii) obtaining surface-active antibodies by chemical or physical attachment of hydrophobic groups to the antibodies, and (iv) mixing the surface-active antibody with the emulsion.
