Expression analysis of recombinant peppermint and E.
coli IPK, and partial purification of the E.
coli IPK. SDS/PAGE lanes are: 1, molecular mass markers;
2, peppermint IPK expressed from pBAD-MPK in E. coli
BL21-CodonPlus-RIL cells (induction with 0.02% arabinose); 3,
E. coli background control (pBAD-MPK in E.
coli BL21-CodonPlus-RIL cells (repression with 0.02% glucose);
4, E. coli IPK expressed from pBAD-ECK in E.
coli Top 10 One Shot cells (induction with 0.02% arabinose);
and 5, partially purified E. coli IPK (from 4 above)
after affinity chromatography.
