Affinity measurement for the binding of sifalimumab to IFN-α2A
The dissociation constant (KD) was determined using a KinExa instrument as described under “Experimental Procedures.”
| Molecule | 95% confidence intervala | |
|---|---|---|
| KD | pm | |
| Sifalimumab | 44 | 27–65 |
a The 95% confidence interval indicated the range over which the measured KD is thought to vary due to the reproducibility of the instrument. The residual error between the fitted and theoretical curves was 2.7%.
