Analysis of UL54 protein expression. a The pPAL7 and pPAL7-UL54 were induced to express protein in E. coli Rosetta, BL21 (DE3), BL21 (pLysS). (−) and (+) represent incubation without and with IPTG, respectively. b, c, d UL54 protein was expressed at different temperatures (25, 30, and 37 °C), induction times (2, 3, 4, 5 and 6 h), and IPTG concentrations (0.2, 0.4, 0.6, 0.8, and l.0 mM)
