Webinar Description:

In this symposium, participants will gain a better understanding of the science behind SomaLogic’s “next generation” of protein binding reagents (SOMAmers – Slow Off-rate Modified Aptamers). Through discussion and visualizations, participants will learn how protein-like modifications to nucleic-acid ligands lead to superior protein-binding reagents with slow off-rates, and high binding affinities. The specific structural features of SOMAmer-protein interactions will be discussed via presentation of co-crystal structures of several SOMAmers in complex with their protein targets

Learning Objectives:

  • Development of SOMAmer reagents as protein-binding tools
  • Applications for SOMAmer reagents
  • Description of co-crystal structures of SOMAmers in complex with protein targets
  • Key differences between conventional aptamers, antibodies and SOMAmers, primarily in multiplexing

Who Should Attend:

  • Research and Development Professionals
  • Lab Managers and Directors
  • PI’s
  • Affinity reagent users


Speaker Information

Nebojsa JanjicNebojsa Janjic, PhD, Chief Scientific Officer at SomaLogic Nebojsa Janjic has been the chief science officer at SomaLogic, Inc. since January 2009. Prior to joining SomaLogic, Nebojsa was the CSO at Replidyne, Inc., a biotechnology company focusing on the development of new small-molecule antibacterial agents. Prior to Replidyne, he was senior director of drug discovery at NeXstar Pharmaceuticals. At NeXstar, he was responsible for creating a pipeline of aptamer-based drug candidates for pre-clinical and clinical development. His contributions included the discovery and early development of Macugen, the first-in-class FDA-approved treatment for macular degeneration and Innovative Pharmaceutical Product of the Year in 2005. Nebojsa is also an inventor of Fovista™, an aptamer-based antagonist of PDGF-B currently in late-stage clinical trials for use in combination with VEGF inhibitors in macular degeneration. Nebojsa received his bachelor's degree in molecular biology and Ph.D. in physical organic chemistry from the University of Washington in Seattle and completed his postdoctoral training at the Scripps Research Institute in La Jolla as a Cancer Research Institute Fellow.
