Structure of Fab 297 in complex with influenza H1N1 A/Victoria/4897/2022 neuraminidase
Identification of a seasonal influenza vaccine-induced broadly protective neuraminidase antibody.
20 mM Tris-HCl, 100 mM NaCl, 10 mM CaCl2
Neuraminidase was expressed recombinantly in SF9 cells. Fab 297 was expressed recombinantly in Expi293F cells.
A complex of neuraminidase from influenza A A/Victoria/4897/2022 with human Fab 297
The sample was also mixed with octyl glucoside to 0.1% w/v of the detergent final concentration piror to applying on the grid.
Variable domain of the heavy chain of Fab 297
Variable domain of the light chain of Fab 297
