rGlpQ and rBipA expression and purification. B. turicatae glpQ was expressed as a recombinant fusion protein (A). Lanes 1 and 2 are E. coli BL21 pLysS pET-19b-glpQ before and after induction with IPTG, respectively; lanes 3 and 4 are two purified fractions of rGlpQ. B. turicatae bipA was also expressed as a recombinant fusion protein (B). Lanes 1 and 2 are E. coli BL21 pLysS pET-19b-bipA before and after induction with IPTG, respectively; lanes 3 and 4 are two fractions of purified rBipA. Immunoblotting was performed using an anti-histidine probe conjugated to HRP for the histidine epitope on rGlpQ and rBipA (C). Molecular masses are shown on the left of each immunoblot in kilodaltons. MW, molecular weight; rBipA, recombinant Borrelia immunogenic protein A; rGlpQ, recombinant glycerophosphodiester phosphodiesterase.
