expression in Escherichia coli BL21(DE3). Full-length Icp55 construct can not be expressed in the soluble fraction. Two truncated versions, Icp55t1 with 42 amino acid N-terminal truncation and Icp55t2 with 57 amino acid N-terminal truncation, are successfully expressed in soluble forms. All activity assays for Icp55 are reported for Icp55t1 construct
