Most linker-payloads used for ADCs need to be purified by prep-HPLC followed by lyophilization. Prep-HPLC generates large quantities of product fractions that require a time-consuming lyophilization process. In this poster, we discuss an enrichment process for reducing the volume of the Prep-HPLC pure product fractions to <1/4 of the original volume. As a result, the lyophilization time can be shortened significantly and the decomposition of the linker-payloads can be effectively prevented.
