TABLE 3.

Formulated ELP[V2Y-45] solutions of the three downstream processes were analyzed with regard to the target molecule’s molecular weight, its purity which was calculated from its band intensities in SDS-PAGE, the final target molecule yield, formulation buffer conductivity, and nucleic acid contamination in the final formulation (n = 3).
