| |
| - | <h4>1. Week</h4>
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Finally, the synthesised <i>has</i>2 gene has arrived!

| |
| - | Transformation of electro competent <i>E. coli</i> cells with Eurofins standard delivery plasmid pexK4 containing the synthesised <i>has</i>2 insert DNA.

| |
| - |
| |
| - | <h4>2. Week</h4>
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]First attempt to insert <i>has</i>2 DNA into the multiple cloning site (MCS) of pSMF2.1 plasmid construct. This shuttle plasmid allows on the one hand the amplification of plasmid DNA in high copy numbers in <i>E. coli</i> cells. On the other hand pSMF2.1 is optimised for expression of recombinant proteins in our favourite chassis <i>B. megaterium. Has</i>2 insert DNA was absent in transformants.
| |

| |
| - |
| |
| - |
| |
| - | <h4>3. Week</h4>
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Repetition of cloning experiments (week 2) with new T4 ligase provided many <i>E. coli </i>transformants with pSMF2.1 plasmid construct containing <i>has</i>2 insert DNA.
| |
| - |
| |
| - |
| |
| - |
| |
| - | <h4>4. Week</h4>
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]
| |
| - | Extraction of genomic DNA from <i>B. megaterium</i> was performed.
| |
| - |
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Optimal PCR conditions for the amplification of genomic DNA from <i>B. megaterium </i>were tested. First gene (<i>UDP-glc</i>DH) involved in synthesis of precursor molecules and probably contributing to a high yield production of high molecular mass hyaluronic acid was successfully amplified.
| |
| - |
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]
| |
| - | First attempt for downstream insertion of <i>UDP-glc</i>DH DNA into the MCS of pSMF2.1 plasmid construct that already contained the <i>has</i>2 insert DNA was successful.

| |
| - |
| |
| - | <h4>1. Week</h4>
| |
| - |
| |
| - | *Open day at Saarland University. The iGEM team was proud to present its project to the general public.
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Plasmid preparation and control digestion to confirm the simultaneous presence of <i>has</i>2 and <i>UDP-glc</i>DH insert DNA in the pSMF2.1 plasmid construct.
| |
| - |
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Preparation of fresh protoplasts for transformation of <i>B. megaterium</i> strain MS941 was successful. Competence is outstanding.
| |

| |
| - |
| |
| - | <h4>2. Week</h4>
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Transformations of <i>B. megaterium</i> protoplasts with different pSMF2.1 plasmid constructs were successful. Screening process for the identification of <i>B. megaterium</i> transformants with correct plasmid constructs was time consuming.
| |
| - |
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]<i>B. megaterium</i> chassis for the first ever biotechnological production of high molecular mass hyaluronic acid is ready!
| |
| - |
| |
| - |
| |
| - | <h4>3. Week</h4>
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Cultivation of <i>B. megaterium</i> and induction of recombinant protein production were performed. Samples were prepared after an appropriate cultivation time to check and characterise recombinant protein expression levels of Has2 and UDP-GlcDH.
| |
| - |
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]These samples were also used for viscosity measurement since the outstanding water binding capacity of high molecular mass hyaluronic acid should increase the viscosity of the cultivation medium.
| |
| - |
| |
| - |
| |
| - | <h4>4. Week</h4>
| |
| - |
| |
| - | [[File: Mark BioBrickKL.png|thumb|40px|left]] Illegal restriction sites within <i>has</i>2 and <i>UDP-glc</i>DH were changed via QC-PCR. Resulting biobrick DNAs were inserted into the standard biobrick plasmid construct pSB1C3.
| |
| - |
| |
| - |
| |
| - | [[File: Mark ErlenmeyerKL.png|thumb|30px|left]]Measurement of viscosity was performed. There was no difference in viscosity of the culture medium and consequently no high molecular mass hyaluronic acid production detectable in the first attempt.
