Results:
Gel electrophoresis:
Analysis:
In lane 2 containing pSB1C3 2 bands are detected indicating a succesful digestion of the plasmid (the band at 1000 bp corresponds to J04450). A succesful digestion of the flhD/C cannot be concluded from the gel. However both bands was excised and extracted from gel (Gel extraction)

Transformation of TOP 10 e. coli with ninaB gene in pOT2:chlor vector

Done by: Christian
Transformation of cells with gene in plasmid
Date: 21/7
Methods: Transformation
Protocols: TR1.1 and paperblotter protocol from plasmid cDNA package.
Notes: Filterpaper was washed with 50ul TE buffer for 2 seconds. Paper punch was then transfered to a sterile eppendorff tube, and transformation protocol TR1.1 was followed from here. The usual positive control was used.
Plates were dried for ca. 12 minutes, showed no sign of cracking.
The gene is inserted into a pOT2 plasmid. A plasmid map can be found [http://www.fruitfly.org/about/methods/pOT2vector.html here]:
Two of the chlor plates were damaged (one very slightly) and one ampicilin plate was torn up, again. (good thing two were dried). Plates were incubated ON at 37°.
Include column content here.
