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

Cat No: N3501 Category:

375,00 

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.

This anti-Sars-CoV-2 Spike protein S1 nanobody was developed by the team of Alejandro Rojas-Fernandez at the Institute of Medicine at 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.

FluoTags® can be equipped with a single fluorophore for more quantitative readouts (FluoTag-Q), with two fluorophores per single-domain antibody (FluoTag-X2), and we also developed a blend of two sdAbs bindings simultaneously the target proteins and each bearing two fluorophores (FluoTag-X4). For more detailed information on the FluoTags, please check our Technology Section.

Storing: Vials containing lyophilized protein can be stored at 4 °C for 6 months. We recommend reconstituting the protein with 50 % sterile glycerol including 0.1 % sodium azide as preservative if applicable. Minimize the number of freeze-thaw cycles by aliquoting the reconstituted protein. Long term storage at -80 °C for up to 6 months. Working aliquots can be stored at -20 °C for up to 4 weeks. We do not recommend storing the reconstituted protein at 4 °C.
