Distribution of matrix cluster signals in wild type (WT) and Pex11β knockout (KO) late fetal E19 mouse lung tissue sections from mass spectrometry imaging (MSI) experiments. (A–C) Evenly distributed 4-Nitroaniline (pNA) matrix cluster images in negative-ion mode. (D–F) Evenly distributed 2,5-Dihydroxybenzoic acid (DHB) matrix cluster images in positive-ion mode. Scale bar 500 µm.
