In vivo localization of CKS9 compared with CSK9 in rat small intestinal tissues. Chemically synthesized CKS9 or CSK9 was injected into closed ileal loops, and their tissue-specific localization was monitored using fluorescence microscopy; (A,B) In vivo localization of CKS9 peptides in PP and Non-PP; (C,D) In vivo localization of CKS9 peptides in PP and Non-PP. Green and red fluorescent signals in each panel indicate the location of the peptides and mucus layer in rat small intestinal tissues (closed ileal loops), respectively. Scale bars indicate 50 µm in PP and 20 µM in Non-PP [52].
