Albumin-binding ability of ABD-VP1vaccine. (A) SDS-PAGE and (B) western blot analysis of the recombinant ABD-VP1 and VP1 proteins. (C) The binding abilities of ABD-VP1 and VP1 proteins to albumins were detected by ELISA assays. (D) Serum complex of ABD-VP1 with albumin was detected by ELISA assays. (E) The serum half-lives of ABD-VP1 and VP1 vaccines. VP1 and ABD-VP1 proteins were injected subcutaneously into mice, sera were taken at indicated time points for VP1 amount detection by ELISA assays. The level of serum VP1 protein at 5 min after injection was uniformly quantified as 100%. Individual experiment was repeated 3 times. *P < 0.05; **P < 0.01; ***P < 0.001.
