  • Patent number: 8030458
    Abstract: An IgG1? monoclonal antibody to the immunosuppressive drug tacrolimus has improved properties. In particular, this monoclonal antibody, designated 1H6, has reduced cross-reactivity to several tacrolimus metabolites. This antibody is suitable for performance of immunoassays such as homogeneous immunoassays to detect or determine the presence or concentration of tacrolimus in samples such as blood samples. The invention further includes derivatives of tacrolimus derivatized at a non-binding portion of the molecule useful in immunizing antibody-producing animals and in producing such monoclonal antibodies, as well as labeled derivatives of tacrolimus useful as tacrolimus analogues in such assays. The invention further includes immunoassay methods for the detection of tacrolimus and test kits useful in performing such immunoassays.

  • Publication number: 20110066225
    Abstract: A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.

  • Publication number: 20100100169
    Abstract: A method of modifying a medical device such as a stent with nano-constructs is disclosed. The method comprises applying a first fluid to the stent; immersing the stent being wet from the first fluid into a second fluid having a suspension of nano-constructs; and removing the stent from the second fluid and allowing the first and second fluid to be removed such that the nano-constructs are carried by the stent for in vivo application of the constructs to a target location of a mammalian subject. The nano-constructs can be attached to the surface of the stent, can be attached to a surface of the coating of the stent, can be embedded into the stent, or can be embedded into the coating.

  • Patent number: 7635571
    Abstract: Methods are disclosed for determining minute quantities of an analyte in a medium suspected of containing the analyte. One method comprises treating a medium suspected of containing an analyte under conditions such that the analyte, if present, causes a substrate having an oxidant cleavable linker and a photosensitizer to come into close proximity. The photosensitizer generates singlet oxygen which oxidatively cleaves the linker to form a product which can be detected in a sandwich detection assay such as LOCI. The amount of product detected is related to the amount of analyte in the medium. Compositions, kits, and compounds are also disclosed.
