Western blot analysis of the pro-CLS-matWT and pro-CLS-matS805A variants. Medium samples <t>of</t> <t>COS-1</t> cells transfected with pSec-pro-CLS-matWT alone (CLS-WT), pSec-pro-CLS-matWT and pSec-HAI-1NIK1LK2 (CLS-WT + HAI-1), pSec-pro-CLS-matS805A alone (CLS-S805A) and pSec-pro-CLS-matS805A and pSec- HAI-1NIK1LK2 (CLS-S805A + HAI-1) were subjected to reducing SDS-PAGE. After western transfer, the blot was probed with Spr992 or S-protein–HRP. The position to which pro-CLS-matWT and pSec-pro-CLS-matS805A migrated is indicated as ‘Proforms’ to the right of the right panel. The position to which HAI-1NIK1LK2 migrated is indicated to the right of the right panel. The molecular masses of the marker proteins are indicated in kilodaltons to the left of the left panel.
