Publication number: 20140081007Abstract: This invention relates to non-radioactive markers that facilitate the detection and analysis of nascent proteins translated within cellular or cell-free translation systems. Nascent proteins containing these markers can be rapidly and efficiently detected, isolated and analyzed without the handling and disposal problems associated with radioactive reagents. Preferred markers are dipyrrometheneboron difluoride (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) dyes.Type: ApplicationFiled: August 22, 2013Publication date: March 20, 2014Applicant: Ambergen, Inc.Inventors: Kenneth J. Rothschild, Sadanand Gite, Jerzy Olejnik

Patent number: 8663951Abstract: A method for producing picornaviral capsid protein complexes (e.g., picornavirus like particles) in E. coli using a small-ubiquitin-related fusion protein expression system and an E. coli strain used in practicing this method. Also disclosed is use of the picornaviral capsid protein complexes like thus prepared for eliciting immune responses.Type: GrantFiled: January 7, 2010Date of Patent: March 4, 2014Assignee: Academia SinicaInventors: Ting-Fang Wang, Shu-Mei Liang
