3235637-0	1988	Determination of pterins in urine by high-performance liquid chromatography on C18 columns conditioned with cetyltrimethylammonium bromide.	Pterins	17-24	Bardet-Biedl syndrome 9	Homo sapiens	79-82	
3235637-1	1988	A method is proposed for the determination of pterins in urine without clean-up by reversed-phase high-performance liquid chromatography on a C18 column previously conditioned with cetyltrimethylammonium bromide.	Pterins	46-53	Bardet-Biedl syndrome 9	Homo sapiens	142-145	
24412699-5	2014	Eight pterins were successfully separated on HILIC Luna diol-bonded phases, Aquasil C18 RP column and LiChrospher C8 RP column.	Pterins	6-13	Bardet-Biedl syndrome 9	Homo sapiens	84-87
