Figure 5A. Comparison of the reduced and alkylated TNK-tPA from the innovator and follow-on manufacturers by SDS-PAGE separation. The resolved single and 2-chain forms with their associated glycosylation such as type I (3 glycosylation sites) and type II (2 glycosylation sites) are indicated with squares and arrows in the figure.
Figure 5B. Comparison of the reduced and alkylated TNK-tPA (with and without PNGase F treatment) from the innovator and follow-on manufacturers by SDS-PAGE separation. The resolved single and 2-chain forms with their associated glycosylation such as type I (3 glycosylation sites) and type II (2 glycosylation sites) or deglycosylated forms (with PNFase F treatment) are indicated with squares and arrows in the figure.
