Publication number: 20150259535Abstract: 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: ApplicationFiled: December 29, 2014Publication date: September 17, 2015Inventors: Zhenjun Diwu, Jianheng Zhang, Yi Tang, Xiang Guobing
-
Patent number: 9006469Abstract: 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.Type: GrantFiled: April 17, 2013Date of Patent: April 14, 2015Assignee: AnaSpec IncorporatedInventors: Zhenjun Diwu, Jianheng Zhang, Yi Tang

Patent number: 8569452Abstract: 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.Type: GrantFiled: February 10, 2012Date of Patent: October 29, 2013Assignee: American Peptide Company, Inc.Inventors: Baosheng Liu, Jianheng Zhang
