Average holdup BI: 0.05
Normalized holdup BI: 0.05
Immobilized partner concentration in holdup experiment (10-6M): 18
Experiment method: DAPF_holdup
Details of affinity fitting: fluorescein + mCherry internal standards + normalization based on CALIP_holdup data + reverse layout
Experimental details: The peptide stock solution had solubility issues. The peptide concentration in the affinity conversion step may differ from reality causing a systematic error in reported affinities.
