2.3. Western blotting
The electrophoresed gel was blotted onto a
nitrocellulose membrane (pore size, 0.1 mm) inblotting buffer (3.03 g Tris base, 14.4 g glycine,
and 200 ml methanol per liter) at 100 V for 1 h.
The membrane was then rinsed in PBS (pH 7.4),
soaked in 5% skim milk (in PBS) for 1 h, and
rinsed in PBS for 5 min. The membrane was
treated with 1:1000 dilution of the the primary
antibody (either a polyclonal hyperimmune anti-
YHV IgG or anti-CBV IgG) for 1 h, rinsed 3
with PBS for 5 min,
