"Helper" = E. coli strain carrying pRK2013 or some other helper plasmid that will promote mobilization of broad host range plasmid. pRK2013 will not replicate in Agrobacterium and many other recipients. "Recipient" = Agrobacterium or Rhizobium, often grown on LB at 28oC, or .

High-efficiency electro-transformation of E. coli. ---D. Tantin 7/7/93. This protocol should give routine efficiencies of 108 colonies/ g DNA (Derived Verbally from the Great Tian “just use 1 ” Chi) Preparation of cells. Inoculate LB+ and grow to O.D. 600nm of ~.6.
Molecular Biology Protocols Transformation
When expressing proteins (specifically use BL21 E.coli cells), check O.D.600 until it reads between 0.4-0.8, add 100ul 100mM IPTG (inducer). Take 500ul samples at 0h, 4h, 12h, 24h…..(spin down and discard supernatant. Store in -20˚C) to check on SDS-PAGE gel. Day 3:

This protocol differs from other procedures in that the bacterial culture is grown at 18ºC rather than the conventional 37ºC. Otherwise, the protocol is unremarkable and follows a fairly standard course. Why growing the cells at low temperature should affect the efficiency of transformation is anybody's guess.
