- All values represent the average of at least three trials with the associated standard deviation
-
aKd(1M) is the affinity at 1 M NaCl, which represents the specific, non-electrostatic component of binding
-
bZeff is the number of Na+ ions released upon protein binding, and reflects the number of electrostatic contacts between protein and RNA
