TABLE 2.

IC50 values for the competitive binding of 125I-[His5,D-Tyr6]GnRH with GnRH agonists in COS-1 cells transiently transfected with the H. burtoni GnRH-R

Peptide IC50 (nM)
[His5,Trp7,Tyr8]GnRH (GnRH2) 14.2 ± 5.5
[Trp7,Leu8]GnRH (GnRH3) 2486.7 ± 888.7
[Arg8]GnRH (mGnRH1) 2615 ± 2821.4
[Ser8]GnRH (sbGnRH1) 30233.3 ± 8575.7

Data are calculated as the mean of three separate experiments.
