"WebAs a rough guideline, peptides with IC 50 values <50 nM are considered high affinity, <500 nM intermediate affinity and <5000 nM low affinity. Most known epitopes have high or intermediate affinity. Some epitopes have low affinity, but no known T-cell epitope has an IC 50 value greater than 5000. " - The ic50 value
