As expected, only very minor differences were noted between the antibodies with and without LS (Table 1 , Suppl Table S1 A,B), with highly significant correlation between values: for each pair of antibodies, both IC50 values and IC80 values correlated with Spearman’s rho of 0.94 or higher and p < 0.0001; and the median IC50s were no more than twofold different, which is within experimental error for this assay 17 .
