Notes on error determination |
In order to measure Kd values for tight binding inhibitors, acetyl pepstatin was used as a competition displacement ligand. Errors determined using non-linear least-squares analysis. |
General comments |
Binding too tight to measure directly.
Data obtained by competition ITC. |
Warnings |
DeltaH (8.79) in range 10.00 to -10.00. It is difficult to interpret ITC data as DeltaH approaches 0. |
