Examples of HPLC of extracts from individual neurons dissected from the cerebral Bn cluster, which was not immunoreactive for CP1 or CP2, and the asymmetric right pleural ganglion cluster, which was positive for CP2-lir but not CP1. Cell extracts were run with HFBA as a counterion, as in Figure 6.Dashed lines indicate the retention times of syntheticCP1, FMRFamide (FMRFa), andCP2 as monitored by absorbance. The identities of FMRFamide and CP2 were confirmed by running aliquots from these peaks on HPLC with TFA as a counterion.
