Jianheng Zhang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20150259535
    Abstract: Chemically reactive carbocyanine dyes that are intramolecularly crosslinked between the 1-position and 3?-position, their bioconjugates and their uses are described. 1,3?-crosslinked carbocyanines are superior to those of conjugates of spectrally similar 1,1?-crosslinked or non-crosslinked dyes. The invention includes derivative compounds having one or more benzo nitrogens.
    Type: Application

    Inventors: Zhenjun Diwu, Jianheng Zhang, Yi Tang, Xiang Guobing
  • Patent number: 9006469
    Abstract: The quenching compounds of the invention are weakly luminescent cyanines that are substituted by one or more heteroaromatic quenching moieties. The quenching compounds of the invention exhibit little or no observable luminescence and efficiently quench a broad spectrum of luminescent compounds. The chemically reactive quenching compounds possess utility for labeling a wide variety of substances, including biomolecules. These labeled substances are highly useful for a variety of energy-transfer assays and applications.

  • Patent number: 8569452
    Abstract: The present invention relates to novel phalloidin derivatives and their fluorescent dye conjugates. These new compounds may be used in studies of actin dynamics in living systems. The present invention also relates to methods for preparing such compounds. The synthesis routes combine solid-phase and solution phase peptide synthesis, and has great advantage for efficient preparation of a diverse library of the phalloidin derivatives, especially for the synthesis of phalloidin.
