dc.description.abstract | Reverse-phase high-performance liquid chromatography (HPLC) resolution and recovery of cytochrome P-450 and bovine rhodopsin, both integral membrane proteins, and large peptides derived from P-450 LM2 were enhanced by utilizing ternary solvents. Surprisingly, most test materials eluted later in the gradient when using mixtures of acetonitrile and propanol in the mobile phase compared to using either solvent alone. Of the supports tested, the best recovery of hydrophobic cytochrome P-450 LM4 was experienced on the less retentive CN-bonded phase. Two alternate solvents for HPLC of polypeptides are proposed: (1) 0.02-0.1 hexafluoroacetone/NH3, pH 7.2 for highly acidic peptides; and (2) 6 formic acid/0.13 trimethylamine, pH 1.5, vs 4 formic acid/0.09 trimethylamine in propanol for relatively insoluble peptides. Anomalous side reactions between formic acid and peptides can cause HPLC peak broadening, increased retention, and decreased resolution. These deleterious effects are thought to be due in part to formyl esterification of serine and threonine residues and appear to be reversible by aminoethanol treatment. | en_US |
