==Newest EcoRI/BamHI Transfer method (7/31/08)==
+
-
 
+
-
Digestion:
+
-
*0.5ul  plasmid in entry vector
+
-
*0.5ul  EcoRI
+
-
*0.5ul  BamHI
+
-
*1ul NEB2 + ATP buffer
+
-
*7.5ul of water
+
-
*incubate the digestion for 1hr. in the thermocycler, and 20 min for heat kill.
+
-
+
-
No purification step.
+
-
+
-
Ligation:
+
-
*1ul of dilute assembly vector (or 0.5ul if undiluted)
+
-
*0.5ul ligase
+
-
+
-
Transform. (same as usual)
+
-
 
+
-
== Transfers from Miniprepped DNA  ==
+
-
(already in correct vectors - transfers into L/R cells)
+
-
 
+
-
In 0.5 ml tube, combine:
+
-
*1ul plasmid dna
+
-
*30ul of cells (L/R) + 30 KCM (no water)
+
-
+
-
Take the reaction, and:
+
-
*sit in ice for 10 min
+
-
*heat shock for 90 sec
+
-
*sit another 2 min ice
+
-
 
+
-
Then, incubate your tubes for 5 minutes (No rescuing is necessary)
+
-
+
-
Next, prepare plates (double antibiotics) and tubes with media (LB + antibiotics)
+
-
+
-
*Take 15ul of rxn. Spot it onto a plate (no spreading required)
+
-
*Take the remaining 15ul into a pipette tip. Drop the entire tip into your tube of media.
+
-
*Let plates and tubes sit overnight.
+
-
*Miniprep the next day.
+
-
 
+
-
 
+
-
==1-2-3 Assembly==
+
-
 
+
-
Set up the digestion:
+
-
*1uL lefty plasmid(methylated)
+
-
*1uL righty plasmid (methylated)
+
-
*1uL NEB2+ATP
+
-
*0.3 uL XhoI
+
-
*0.3 uL BglII
+
-
*0.3 uL BamHI
+
-
*6.1uL Water
+
-
Heat kill at 65 for 20 min
+
-
 
+
-
Add 0.3uL Ligase
+
-
 
+
-
Transform, rescue, plate on dual antibiotic plates
+
