Immunoblot analysis of the antigenicity of recombinant gB proteins in the serum of sea turtles. Five antigenic fragments of gB protein and the fusion tag protein thioredoxin (Thx), which serves as a negative protein for turtle serum, were reacted with either sea turtle serum (A) or the positive control anti-His antibody (B). The gB fragments recognized by the tested sera are indicated with asterisks.
