In preparation for potential ligation failure, once again inoculated liquid cultures of Amp LB  for miniprep with pSB74,P0312,R0011, B0015, and J23114 transformants, making two 5 mL cultures for each plasmid.  When OD reached 0.6, once again made glycerol stocks from 0.5 mL of each solution and 0.5 mL of filter-sterilized 50% glycerol.  This time flash-froze the stocks immediately, rather than waiting overnight as on <a href="http://2010.igem.org/Team:Yale/Our_Project/Notebook/Week_3" 6/23.</a>  <br/>
