text: Yo, check it out, I'm 'bout to spit some knowledge,
  Talkin' 'bout chemical fixation, let me acknowledge,
  The routines used often fail, can't preserve,
  Them delicate membrane-bounded tubular curves.
  
  In immunocytochemical studies, it's a struggle,
  To locate structural proteins, avoid the trouble,
  Fixation procedures degrade those structures,
  Gotta find a way to preserve without ruptures.
  
  Listen up, here's a procedure that's the bomb,
  Preserves the tubular lysosome system, stay calm,
  Stimulated macrophages, they're the key,
  Immunofluorescence localization, you'll see.
  
  This methodology, it's a game-changer, true,
  Assessin' the spatial relationship, it's what we do,
  Tubular lysosomes and microtubules, in sync,
  Macrophages show us how they interlink.
  
  So remember this procedure, it's the way to go,
  Preserve them delicate structures, let 'em glow,
  Fixation ain't a problem when you use this technique,
  Tubular structures safe, that's what I speak.
