Figure 3. Immunoblot analysis of serum samples from brush mice (Peromyscus boylii) and Merriam chipmunks (Tamias merriami) captured at Mt. Wilson Observatory in California, USA. Each sample was tested at a dilution of 1:100 with a whole-cell lysate of Borrelia hermsii MTW-2 isolated from Mt. Wilson (left lane of each membrane) and purified recombinant GlpQ (right lane of each membrane). Results and animal numbers are presented above and below each panel, respectively. Neg, negative; pos, positive.
