Assembly of endosome detection operon

Marcin

Task 1: Prepare the following ligations:

• [http://partsregistry.org/Part:BBa_K177035BBa_K177035] with [http://partsregistry.org/Part:BBa_K177036BBa_K177036] to obtain [http://partsregistry.org/Part:BBa_K177037BBa_K177037]
• [http://partsregistry.org/Part:BBa_K177035BBa_K177035] with [http://partsregistry.org/Part:BBa_K177043BBa_K177043] to obtain [http://partsregistry.org/Part:BBa_K177044BBa_K177044]

Methods:

• Reaction mixtures composition:

45 μl mixture of insert and vector DNA (both are purified at the same probe)
1.5 μl T4 ligase (Fermentas)
5 μl Ligase Buffer (Fermentas)

• Ligation was carried out 20 hours in 16 °C.

Task 2: Transformation of TOP10 chemocompetent bacteria with following constructs:

• [http://partsregistry.org/Part:BBa_K177044BBa_K177044]
• [http://partsregistry.org/Part:BBa_K177037BBa_K177037]

Methods:

• Ligation mixture was thermally inactivated
• Detailed protocol of transformation is described here

Comment:

All performed ligation were unsuccessful. I am afraid that the effectivity of our gel-out kit may be lower than is expected. Someone must find it out.
