Recombinant Antibody Network Partners with Bristol Myers Squibb to Develop Novel Therapies
March 1, 2021
The Recombinant Antibody Network (RAN), a consortium comprising research groups from UC San Francisco (UCSF), the University of Chicago, and the University of Toronto have expanded a previous research collaboration with Bristol Myers Squibb, aimed to create and develop high-performance recombinant antibodies against diverse targets in human cells. The RAN was founded in 2012 by … Continue reading
Patent of the Week: Improving the Performance of Antibody Fragments
July 6, 2020
Patent-of-the-week-improving-the-performance-of-antibody-fragments Antibody fragments, including Fabs, which bind to immune response-triggering substances, or antigens, have demonstrated utility in various research and diagnostic applications. However, their structure limits their use, so researchers have engineered a protein that can be tethered to Fabs to expand their functionality. The inventors, including Anthony Kossiakoff, a professor of biochemistry and molecular … Continue reading
