Area of Science:

  • Analytical Chemistry
  • Biochemistry

Background:

  • Inositol phosphates (IPs) are crucial signaling molecules.
  • Efficient separation of IPs and their isomers is essential for research.

Purpose of the Study:

  • To develop a rapid and reproducible technique for resolving inositol phosphates.
  • To enable quick separation of inositol trisphosphate isomers.

Main Methods:

  • Utilized ACCELL QMA anion-exchange SEP-PAKs with ammonium formate solutions.
  • Combined SEP-PAKs with a rapid isocratic high-performance liquid chromatography (HPLC) procedure (5-6 min).

Main Results:

  • Achieved sample processing and inositol phosphate resolution within minutes.
  • Successfully separated inositol trisphosphate isomers using the combined technique.
