Abstract: Provided is an optical in vivo contrast agent comprising a fluorescent polymeric microsphere, wherein the micro-sphere is impregnated with a dye having an excitation and emission spectrum compatible with in vivo imaging, and wherein the microsphere is coated with a block copolymer.

Abstract: Provided is reagents and methods for non-invasive in vivo imaging wherein the reagents comprise targeted carrier molecules conjugated to a NIB reporter molecule. In one aspect the targeted carrier molecule is an antibody, or fragment thereof that has specificity for an antigen in a living body, animal or human. In one embodiment the antibodes are anti-cancer/tumor marker antibodies, organ specific antibodies, tissue specific antibodies, cell type specific antibodies, cell surface specific antibodies, anti-viral antibodies, anti-bacterial antibodies and anti-pathogenic antibodies. The NIP reporter molecules are any fluorescent reporter molecule compatible with in vivo imaging and generally having an excitation wavelength of at least 580 nm.

Abstract: Compositions, assays, methods, and kits are disclosed for use in applications that utilize oxidation of a chromogenic electron donor such as diaminobenzidine (DAB) to generate a signal. Applications include, but are not limited to, immunohistochemistry, chromogenic in situ hybridization, Western blots, Northern blots, Southern blots, ELISA assays, and microarray detection. The compositions, assays, methods, and kits disclosed herein make use of a novel, stabilized formulation of DAB and a novel, stabilized formulation of hydrogen peroxide.
