text: Yo, check it out, I got a procedure to share,
  Estimating galactocerebroside beta-D-galactosidase with flair.
  Using this new compound, it's straight-up dope,
  6-hexadecanoylamino-4-methylum-belliferyl-beta-D-galactopyranoside, we call it HMGal, yo.
  
  We compared some patterns, let me tell you the score,
  Fluorometric procedure against the spectrophotometric chore.
  With the chromogenic substrate HNGal on one side,
  HMGal boosted sensitivity, it was a wild ride.
  
  We increased it a hundred-fold, ain't that grand?
  Spectrophotometric method couldn't even withstand.
  But that ain't all, we got more to disclose,
  Shorter incubation, less cell protein, we chose.
  
  This procedure, it's got the sensitivity on point,
  Reproducibility too, ain't nothin' to disappoint.
  With HMGal as the substrate, we reached a new height,
  Biochemical diagnosis of Krabbe disease, now that's tight.
