| - | Four forward primers were designed to amplify:
| |
| - | <br> 1.Promoter T7, RBS, CBP and LOVTAP:

| - | The '''recipient IGEM part''' have been chosen: [http://partsregistry.org/partsdb/get_part.cgi?part=BBa_B0010 BBa_B0010], well 13D in the received kit plate 1

| - | '''Inducible LOVTAP biobrick strategy'''
| |
| - | :*Problem to overcome:
| |
| - | :PstI sites in LOVTAP sequence.
| |
| - | :*Our goal:
| |
| - | :Biobrick consisted of LacI promoter-RBS-LOVTAP-Term (in this order).
| |
| - | :*Material:
| |
| - | :Biobrick of LacI promoter, RBS, LOVTAP, Term separately ( LOVTAP obtained from previous section and the rest from iGEM Spring 2009 distribution Kit plate).
| |
| - | :*Strategy:
| |
| - | :LacI promoter-RBS ligation with iGEM protocol (LacI promoter digested with ES, RBS digested with XP, plasmid containing an other antibiotic digested with EP).
| |
| - | :LOVTAP is digested with ES and inserted into Term plasmid (which was digested with EX previously).
| |
| - | :Finally, LacI promoter-RBS digested with ES to be inserted into LOVTAP-Term plasmid, digested with EX.

| |
| - | '''Partial digestion strategy'''
| |
| - | :* Problem to overcome:
| |
| - | :PstI sites in LOVTAP sequence -> Impossible to use iGEM protocol for ligation (where downstream part must be cut with XP)
| |
| - | :* Strategy:
| |
| - | :Cut with X first.
| |
| - | :Divide into several solutions and add different concentrations of P (by dilution series)
| |
| - | :*Results:
| |
| - | :Most concentrated tube: all P sites are recognized and cut, so the number of parts diminishes with the concentration value.
| |
| - | :Run an agarose gel and extract the right piece (recognized by the segment's length).

| |
| - | '''TRP promoter biobrick strategy'''
| |
| - | :* Problem to overcome:
| |
| - | : SpeI sites on Trp promoter sequence and it's an upstream part which has to be cut with ES.
| |
| - | :* Strategy:
| |
| - | : PCR: Forward primer having E and X sites and Reverse primer NheI.
| |
| - | : Digest Trp promoter with E and NheI.
| |
| - | : Digest plasmid with E and X.
| |
| - | : Ligation -> E site is recreated; X and NheI have compatible ends so ligation is possible and the site is destroyed (mixted site).
