text: Yo, check it, I got a method straight to mention,
  Generating CsI cluster ions, it's my intention.
  In MALDI MS, we goin' big, no doubt,
  Up to m/z over 20,000, we bringin' it out.
  
  Positive or negative, we got it all covered,
  From one MALDI spot, no need to be smothered.
  With CsI(3) and DCTB matrix in the mix,
  Calibration ions poppin', we fixin' the tricks.
  
  In the positive mode, we see a major vibe,
  [(CsI)(n)Cs](+), that's how we thrive.
  For the negative ions, we got the game,
  [(CsI)(n)I](-), spreadin' love, no shame.
  
  Both series of clusters, they evenly glide,
  Every 259.81 units, we ride.
  This easy method we drop, it's a sensation,
  CsI cluster ions for MALDI MS calibration.
  
  Yeah, we bringin' the science, the innovation,
  With a rap twist, we change the presentation.
  But the content remains, no need to worry,
  CsI cluster ions, the future's never blurry.
