    • r for peptides without His/Met residues, a large excess of the respective peptide (final concentration: 300-500 μM) was mixed with the receptor (final concentration: 25 μM) and the indicator (final concentration: 25 μM).

    • note
    • The largest relative changes in absorption are observed at 599 nm but owing to reasons of sensitivity (larger absolute changes) it is advantageous to perform the assay at 504 nm or at ∼580 nm (see Figure 1).
