This is a part for the precise quantification of UV-radiation or radioactive radiation in <i>E.coli</i> (recA+) strains, i.e. BL21(DE3).

This is a part for the precise quantification of UV-radiation or radioactive radiation in <i>E. coli</i> (recA+) strains, i.e. BL21(DE3). It consists of a RecB promoter (<a href="http://partsregistry.org/Part:BBa_K862003" class="external text" title="http://partsregistry.org/Part:BBa_K862003 rel="nofollow">BBa_K862003</a>) fused to a LacZ reporter cloned in front of a double terminator (<a href="http://partsregistry.org/Part:BBa_K173004" class="external text" title="http://partsregistry.org/Part:BBa_K173004 rel="nofollow">BBa_K173004</a>).</td><td><a href="http://partsregistry.org/Part:BBa_K862002" class="external text" title="http://partsregistry.org/Part:BBa_K862002" rel="nofollow">BBa_K862002</a></td><td> Measurement

The RecB promoter sequence was obtained from the <i>E.coli</i> MG1655 genome sequence (<a href="http://ecoliwiki.net/colipedia/index.php/recB:Gene">http://ecoliwiki.net/colipedia/index.php/recB:Gene</a>). We assumed the main promoter region to be located from -70 to -1 bp upstream the recB start codon. Therefore this sequence was synthesized and cloned on an oligo basis.

We will not submit the physical DNA of this part, but we provide the oligo-sequences you can use for synthesizing and cloning this part in front of any EcoRI/XbaI predigested reporter part.
