Other Supplementary Material for this manuscript includes the following:

  • Table S1 (Microsoft Excel format). 9E10 shows a larger signal variability than 4A6 in a single-substitution scan of Myc peptide contexts NGST or LRKR.
  • Table S2 (Microsoft Excel format). 9E10 shows a larger signal variability than 4A6 in a double-substitution scan of the first two amino acid positions C terminal to Myc peptide.
  • Table S3 (Microsoft Excel format). Highest- and lowest-scoring Myc context peptides in a double-substitution scan for clones 4A6 and 9E10.
