Figure 1: Expression and antigenicity of phage-displayed kpvqhalltplgldr peptide.

(A) SDS-PAGE (20%) of recombinant phage. Lane 1, protein markers; lane 2, recombinant phage displaying the kpvqhalltplgldr peptide; lane 3, wild-type phage. (B) Western blot analysis of the recombinant and wild-type phages with infected mouse serum containing antibodies to a 70-kDa protein band or with the serum from a control mouse. Lane 1, recombinant phage was probed with infected mouse serum; Lane 2, wild-type phage was probed with infected mouse serum. Lane 3, recombinant phage was probed with normal serum. Lane 4, wild-type phage was probed with normal serum.
