Mean KD value by variant

Variant Mean KD value (M [95% CI]) fora:
Tixagevimab Cilgavimab
D614G 7.57E−10 (5.4E−10, 1.1E−9) <1E−12 (NE)
Wild-type 4.91E−10 (3.4E−10, 6.9E−10) <1E−12 (NE)
S494L:D614G 8.55E−10 (6.0E−10, 1.2E−9) 1.59E−8 (1.1E−8, 2.2E−8)
K444R:D614G 5.37E−10 (3.8E−10, 7.5E−10) NA (NE)
F486S:D614G NB (NE) <1E−12 (NE)
F486W:D614G NA (NE) <1E−12 (NE)
a

KD, equilibrium dissociation constant; M, mol/L; CI, confidence interval; NE, 95% CI was not evaluable; NA, not available due to poor binding with inaccurate curve fitting; NB, no binding. 1E−12 M was used for KD values of <1E−12 M, and 95% CI was not calculated for variants with a mean KD of <1E−12 M.
