CELA3B was present in sterile-filtered supernatant of human stool derived from heathy individuals. This representative immunoblot shows the presence of chymotrypsin-like elastase 3B (CELA3B) in tested samples (n = 6); however, for some, this was in very low amounts (n = 2). Recombinant CELA3B served as reference. The band showcasing CELA3B is indicated by arrow. Molecular weight (MW) is indicated in kilodaltons (kDa) based on the migration of the molecular marker.
