Tacalyx and Leiden University Medical Center join forces to target tumor-specific glycans in colorectal cancer

A €500k Health~Holland grant funds a collaboration with Prof. Manfred Wuhrer's team on the O-glycome of colorectal cancer.

Tacalyx has entered into a collaboration with Prof. Manfred Wuhrer and his team at the Center for Proteomics and Metabolomics of the Leiden University Medical Center (LUMC). The project is funded with over €500k by Health~Holland.

It builds on LUMC's work defining the O-glycome of colorectal cancer. Tacalyx will use the glycan structures identified there to generate and validate novel antibodies for diagnostic and therapeutic use.

"Tumor-specific glycans as identified by the LUMC are exclusively expressed on many cancers which expectedly will allow higher doses and longer treatment durations with less side effects."

— Dr. Peter Sondermann, co-founder
