Today i understood that running the gel with ligated products is unnecessary which is clear in the below gel. I must not do this mistake again. I plated the transformed colonies on the plate.

Calin

Knockout day. [http://openwetware.org/wiki/NanoBio:_Protocol_for_gene_knockout NanoBio: Protocol for gene knockout]

Made 1M l-arabinose stock. 150mg into 0.85 mL ddH20.

Digested CE with EcoRI (10uL DNA).
