Supplementary Figure 5: Luminescence measurements during the cross-linking reaction of luciferase.

Shown is the decrease in luminescence during the cross-linking reaction (green line, +XL) compared to the positive control (blue line, -XL), both in presence of luciferin (LUC) and ATP. The yellow line shows the negative control (no luciferin and ATP). Data presented as mean ± s.d.
