Reactivity of rabbit antisera in Western blotting. Rabbit antisera (FS0169, FS0191, FS0046, FS0048, FS0170 and FS0610) were produced using synthetic peptides derived from EBOV, SUDV, TAFV, BDBV, RESTV and MARV, respectively. Experimental conditions were the same as in Fig. 1. EBOV (Z), SUDV (S), TAFV (T), BDBV (B), RESTV (R), MARV Angola (A), MARV Musoke (M), MARV Ozolin (O), MARV Ci67 (C), RAVV (Ra). Mo, mock-infected.
