Virusys DryCoat Assay Stabilizer is a mixture of non-toxic components that greatly enhances the long term stability of many immobilized antigens and antibodies. The solution is supplied ready to use and in most cases, can replace your current blocking solution. When properly applied, immunoassay plates or membranes may be completely dried, while sacrificing little, if any, of the activity of the fully hydrated protein. Your own blocking protein is added just before use. Best for assays that have been developed with unusual blocking proteins or protein blends.
