Detection of Zn-containing proteins in slug (Genus Arion) tissue using laser ablation ICP-MS after separation by gel electrophoresis

► The distribution of total Zn in a section of a slug is mapped by LA-ICP-MS. ► Zn-containing proteins are separated by one-dimensional gel electrophoresis. ► Zn-containing proteins are detected by MALDI-TOF-MS. ► This paper demonstrate the potential of LA-ICP-MS in metallomics.
