Removal of insertion in BioBrick suffixes

An insertion between SpeI and PstI present in IgGp, bFGF, ProtA, yCCS and SOD needs to be removed before submission to the Registry. This will be done by digestion with SpeI (inside insertion) and moving digested gene into a new vector.

Digestions

No sample of SOD available for the moment, so this will be digested after plasmid prep.

Results
Relevant-sized for all samples showing successful (but incomplete) digestion. Proceeded to gel extraction.

Gel extraction

Loaded remaining 17 μl of each sample on a new 1 % agarose gel. Relevant bands excised by gel extraction and saved in -20 ° for later purification.

ON culture

Set ON culture of pSB1C3.SOD for later plasmid prep.

  • Standard colony PCR settings.
  • Elongation: 1:30 (too short?)

Gel verification

Colony PCR gel verification of BL21 with pEX carrying the nCPP⋅SOD/yCCS operons.
