The binding affinities of the nAb panel to the RBD by SPR. (a) Examples of binding affinities of CB6 to spike RBD of Wuhan strain (WT) or the N501Y mutant. (b) Summary of the binding affinity data from the indicated mAbs, with the values presented as mean ± SD of three independent experiments. The horizontal dashed lines indicate the threshold of fourfold difference
