Abstract

The invention relates generally to colloidal particle having a core material and a gelatin/aminodextran coating with pendent functional groups attached thereto. Biological substances or molecules, especially monoclonal antibodies, may be attached to said particles. The monoclonal antibody containing particles are useful in a variety of positive and negative biological assays.
