HAWK Biosystems

HAWK Biosystems, formerly Fastbase Solutions, is a Spain-based biotechnology and diagnostics company developing spatial functional proteomics tools for research and clinical applications. Its core platform, QF-Pro®, is an antibody-based FRET-FLIM technology that quantifies protein function, protein-protein interactions, and post-translational states directly in tissue samples with high spatial resolution. The company is focused particularly on immuno-oncology and companion-diagnostics-style applications, including assays for PD-1/PD-L1 checkpoint engagement in non-small cell lung cancer. In addition to the QF-Pro® assay chemistry, HAWK offers related software, reagent kits, and the Violet 3.0 benchtop imaging system. The business appears to operate as a platform and biomarker-enablement company rather than a traditional therapeutics developer.
