Example of MALDI matrix spotting on the nucleus accumbens. Matrix solution (0.06 μl) consisting of 15 mg/ml sinapinic acid in 50% acetonitrile/0.3% TFA was manually spotted in triplicate on the NAc for MALDI profiling experiments (A). For MALDI tissue imaging analysis, automated matrix deposition was carried out using a Portrait 630 acoustic reagent multispotter. Forty passes of one spot (170 pl) per pass of 15 mg/ml sinapinic acid in 50% ACN/0.3% TFA were applied with a center-to-center spot distance of 200 μM (B). ac, anterior commissure; cc, corpus callosum; Str, ventromedial striatum. Scale bar = 1 mm.
