Separation of brain monosialoganglioside molecular species by high- performance liquid chromatography
H Kadowaki, JE Evans and RH McCluer
A method for the separation of molecular species of brain
monosialogangliosides by high-performance liquid chromatography is
described. GM4, GM3, GM2, and GM1 were purified from human brain and their
individual molecular species were separated on a C18 reversed- phase
column. Peaks were identified by mass spectrometry of the intact
ganglioside, by gas-liquid chromatography of the fatty acids, and by
high-performance liquid chromatography of the long chain bases. A
characteristic elution sequence of molecular species permitted their
identification based upon their retention times on the reversed-phase
column.
