The 1-min average mass spectra of 10 μg/mL of kisspeptin-10 (A) and SP (B) in 50% ACN/0.1% FA under positive electrospray ionization (ESI and the CID mass spectra of the doubly charged molecular ion of kisspeptin-10 at m/z 652.04 with 23% collision energy showing the base peak b2 ion at m/z 277.76 (C) and the doubly charged molecular ion of SP at m/z 674.60 with 30% collision energy showing the base b2 ion at m/z 253.81 (D), which was chosen for the selected reaction monitoring (SRM) of kisspeptin-10 and SP, respectively.
