Serologic reactivity of recombinant EF-Tu (rEF-Tu) in infected mice and Lyme disease patients. (A) SDS-PAGE showing purified recombinant EF-Tu protein. Predicted size and observed size for B. burgdorferi EF-Tu is 43 kDa and 47 kDa, respectively. (B) Immunoblotting of rEF-Tu using sera collected from C3H/HeN mice infected with B. burgdorferi strain 5A4NP1. Mouse sera used were collected at 2, 3, 4, 6 weeks of post-infection (1:600 dilution). *, HS stands for hyperimmune sera from mice immunized with rEF-Tu (αEF-Tu, 1:10000 dilution). ^, N stands for sera from naïve mice (1:600 dilution). (C) Representative immunoblotting results showing serologic reactivity of rEF-Tu in Lyme disease patients. Strips C-K are rEF-Tu probed with sera from ten different Lyme disease patients randomly selected from the CDC Lyme disease patient sera panel (1:100 dilution).
