Verification the character of the UL55 polyclonal antibody. A. SDS-PAGE analysis of the anti-pUL55 serum and purified anti-pUL55 serum. M: Molecular mass marker; Lane 1, The IgG proteins of UL55 antiserum examined by SDS-PAGE; Lane 2, The purified IgG of pUL55 examined by SDS-PAGE. H and L indicated the position of heavy and light chains of the IgG proteins, respectively. B. The renatured pUL55 was recognized by purified anti-pUL55 serum. M: Prestained Protein Molecular Weight Marker; Lane 1, the renaturated UL55 protein was analyzed with purified anti-pUL55 IgG; Lane 2, the renaturated UL55 protein was recognized by pre-serum.
