FluoTag-Q anti-SARS-CoV-2 Spike protein S1

FluoTag-Q anti-SARS-CoV-2 Spike protein S1

This anti-Sars-CoV-2 Spike protein S1 nanobody was developed by the team of Alejandro Rojas-Fernandez at the Institute of Medicine from the Universidad Austral de Chile. We acquired the exclusive license to produce this nanobody and make it available for research and development purposes. The FluoTag-Q anti-SARS-CoV-2 S1 is based on the W25 clone, which has a sub-nanomolar affinity for the SARS-CoV-2 S1 protein receptor binding domain (RBD) and can neutralize infections as it efficiently competes with ACE-2 receptor binding.
