Abstract: Assays, e.g., homogenous assays, and methods for identifying, quantifying and/or monitoring the formation and/or stability of a multimeric complex, e.g., a ternary complex are disclosed. The methods and assays of the invention can be used to identify and/or evaluate agents (e.g., proteins, peptides, antibody molecules, and small and large molecules) that interfere with and/or inhibit the formation of a multimeric complex (e.g., a ternary complex) or that disrupt a previously formed complex.

Abstract: A device when attached to a regular kitchen knife that serves as a wedge between the food slice and the knife surface and therefore separating the food slice from the knife surface during a cutting process comprising a stainless steel shell with a curved edge and a convex surface, magnets and rubber stripes fixed together so that this device can be used as an attachment to a knife surface by attraction between the magnets and the ferromagnetic steel knife blade. The rubber stripes provide additional friction between the attachment and the knife surface and prevent sliding of the attachment during cutting. The bubble-like convex surface of the steel shell further prevents food sticking on the surface of the device. The device can be easily attached to and removed from a knife blade.
