 +
1 ul MilliQ added to 30 ul of C43+ET20 competent cells as a negative control
 +
 
 +
Followed the transformation in home-made competent cells protocol and made six plates with each 100 ul:
 +
pUC19 in C43+ET20 (ampR and camR):
 +
Ampicillin - some growth
 +
Chloramphenicol - some growth
 +
Amp and Cam - lots of growth
 +
MQ in C43+ET20 (camR):
 +
Ampicillin - no growth
 +
Chloramphenicol - some growth
 +
Amp and Cam - no growth
 +
 
 +
This means the cells are competent, but the efficiency is low.</p>
