Distribution of feline foamy virus Gag, Bet and Env antigens seroreactivity in 223 domestic cats from Poland. Dashed red lines indicate determined cut-off values

Detection of FFVfca-specific antibodies by immunoblotting assays with a cellular antigen in representative feline serum samples. M – prestained protein ladder; A – lane with Crandell-Rees feline kidney cells (CRFK)/FFVfca cells lysate as antigen; B – lane with uninfected CRFK cells lysate as antigen; P – FFVfca positive control serum; N – FFVfca negative control serum; 34/64, 34/79, 34/15 – representative samples with their ELISA reactivity to FFVfca Gag antigen (OD Gag)
