(A) Schematic illustration of single-neuron releasate collection with a particle-embedded monolithic capillary. Both the stimulant-delivering capillary and the particle-embedded monolithic capillary ends are positioned near the target neuron. (B–D) MALDI MS spectra shown for neuronal releasates collected both pre-stimulation (showing few if any peaks) and collected during/after chemical stimulation of the neuron: (B) Bag cell neuron releasates with acidic peptide (AP) at m/z 2959.7 and egg-laying hormones (ELH) at m/z 4383.0 labeled; (C) individual unknown pedal neuron, with the peak at m/z 1538.6 being pedal peptide; (D) individual B1/B2 neuron release showing the expected small cardioactive peptides A (SCPA) at m/z 1277.7 and B (SCPB) at m/z 1141.6.
