Purification of Lysozyme Inhibitors. Hexa-His tagged Ivyc,
Ivyp, and E. coli MliC proteins were obtained using similar procedures.
Genes coding for Ivyc and E. coli MliC were amplified from E. coli
JM105, and that for Ivyp from P. aeruginosa strain PA01. Expression
vectors pET26b-Ivyc-his, pET26b-Ivyp-his, and pET26b-MliC-his
were constructed and subsequently transformed into Shuffle T7
Express cells (New England Biolabs, USA) and produced as described
previously.
