NLuc-GLP-1R Affinity for GLP-1(7-36) and α/β/γ-Analogues 7 and 8.

NLuc-GLP-1R Affinity
Peptide pIC50 IC50 (nM) IC50 relative
GLP-1(7-36) 7.3 ± 0.04 54 1
7 6.7 ± 0.05 200 4
8 6.1 ± 0.05 850 16

Competition NLuc-GLP-1R pIC50 and IC50 values are the average of ≥3 independent experiments. pIC50 indicates the negative logarithm of the half-maximal inhibitory concentration (IC50). IC50 relative indicates binding affinity normalized to GLP-1(7-36) by the quotient (α/β/γ-analogue/GLP-1(7-36)).
