  • Patent number: 9273089
    Abstract: Composite probes for super resolution optical techniques using super resolution via transiently activated quenchers (STAQ) include a donor moiety and an acceptor moiety joined by a linker, wherein the acceptor moiety, when excited by incident radiation, is excited to a state which, for example, absorbs in the donor emission region, such that the acceptor moiety in its excited state quenches at least a portion of the donor moiety emission. Other transiently activated quenching mechanisms and moieties could accomplish the same task by reducing donor population. Also disclosed are methods for irradiating a selected region of a target material including the composite probe, wherein the composite probe enables improved resolution by point spread function modification and/or nanoscale chemical reactions.

  • Patent number: 7943343
    Abstract: The present invention relates to a bi-specific antibody or antibody fragment having at least one arm that is reactive against a targeted tissue and at least one other arm that is reactive against a targetable conjugate. The targetable conjugate encompasses a hapten to which antibodies have been prepared. In preferred embodiments, the hapten is histamine-succinyl-glycine (HSG). In more preferred embodiments, the at least one arm comprises the CDR sequences of the HSG-binding 679 antibody. The targetable conjugate is attached to one or more therapeutic and/or diagnostic agents. The invention provides constructs and methods for producing the bispecific antibodies or antibody fragments, as well as methods for using them and kits comprising them.
