9570850-4	1998	The major DNPH-labeled product was isolated from the native insulin on reverse-phase HPLC, using trifluoroacetic acid/water/acetonitrile gradients.	acetonitrile	124-136	insulin	Bos taurus	60-67	
1823188-1	1991	Two-dimensional NMR spectra have been recorded for bovine insulin at low pH in acetonitrile/water mixtures.	acetonitrile	79-91	insulin	Bos taurus	58-65	
1823188-6	1991	Similarly, for bovine insulin the chemical shifts in a trifluoroethanol/water solvent mixture are comparable to those observed in acetonitrile/water.	acetonitrile	130-142	insulin	Bos taurus	22-29
