Minipreps
> Check with KpnI/NcoI digests
--> pSB31 KpnI is located 142 bp upstream of EcoRI cloning site (according to pdf map)
--> BioBrick constructs have 2 internal NcoI sites

--> Conclusions: KpnI digestion unclear; successfully identified KAH160/pSB31 clone; continue w/ picking more KAH165/pSB31 clones before sending plasmids in for sequencing.
--> ID'ed two promising KAH165/pSB31 clones; send five putatives off for sequencing (1/26/11 Snow emergency: Genewiz not picking up orders until further notice)
