we report the isolation and characterization of an apolipoprotein a-i mutant using a new technique for structural analysis of apolipoproteins based upon the combined techniques of protein isolation by isoelectric focusing in immobilized ph-gradients , reversed-phase hplc of tryptic peptides , and subsequent molecular weight analysis of isolated peptides by time-of-flight secondary ion mass spectrometry ( tof-sims ) .
