New Born Screening Kit


Jasem’s newborn screening of amino acids and acylcarnitines extracted from a single of a dried-blood spot (DBS), with stable-isotope-labeled internal standards and without derivatization, can be performed with 3.5 min of instrument time.

Key Application

  • Analysis from DBS extraction without derivatization
  • Profile of amino acids&free carnitine/acylcarnitines could be modified/widened for clinical applications
  • Consisting of three scan types-Precursor Ion, Neutral Loss and MRM in the sequence
