The use of sequential high-performance liquid chromatography and capillary zone electrophoresis to separate the glycosylated peptides from recombinant tissue plasminogen activator to a detailed level of microheterogeneity.

Abstract excerpt

The advantage of using the two-dimensional separation method was demonstrated by the separation of the complex tryptic peptides of recombinant human tissue plasminogen activator (rt-PA) glycoprotein. This method hybridizes two analytical methods where fractions containing glycopeptides are collected from reversed-phase high-performance liquid chromatography (RP-HPLC) and separated by capillary zone...
