Lab Diary
Thu 12th July
- IPTG induced GFP revived ([http://partsregistry.org/Part:BBa_J04430 BBa_J04430])
- Test biobrick revival process
Fri 13th July
- Alfalfa Seeds Planted (in Agar)
- Growing alfalfa plants, to get leaves from which to extract DNA for the caffeic acid-3-o-methyltransferase gene (part of the vanillin synthesis pathway)
- Biobricks [http://partsregistry.org/Part:BBa_E0241 BBa_E0241] and [http://partsregistry.org/Part:BBa_J45700 BBa_J45700] revived, using modified protocal from open wetware site
Mon 16th July
- Begin DNA extraction from Bamboo
- Test DNA extraction process from plants
- Prepared mini preps for GFP and mint genes
Tue 17th July
- Alfalfa Transferred to compost
- DNA containing GFP and mint genes extracted from E.Coli
Wed 18th July
- Double digest GFP and mint mini preps, using restriction enzymes SpeI and EcoRI. These were then run on a polyacramide gel
- Biobrick ECFP [http://partsregistry.org/Part:BBa_E0422 BBa_E0422] revived and transformed into E.coli JM109 competent cells
Thu 19th July
- Repeat of double digest (using SpeI & EcoRI) of GFP and mint mini preps with increased concentration of DNA
- Replate colonies of ECFP, 4 overnight cultures prepared for making DNA mini preps
- designed primers for COMT gene (part of vanillin biosynthesis pathway)
Fri 20th July
- Prepared GFP and winter green biobricks for sequencing
- Revived Pseudamonas fluorescens from freeze dried culture (P. fluorescens contains two genes, ech and fcs, which are part of the synthetic vanillin biosynthesis pathway)
- Made 4 mini preps of ECFP
- Designed primers for ech and fcs genes
- Ordered Saccharothrix espeanensis from DSMZ culture collection, which contains Sam5 and Sam8 genes required for the synthetic vanillin biosynthesis pathway
Mon 23rd July
- Ran gels for ECFP mini preps
- Restriction digested using XbaI and PstI
- Alfalfa growing well - now have enough leaf material from which to extract DNA
Tue 24th July
- Annealed dif F & R oligoes, restriction digested with SacI & SpeI, ligated with BioBrick vector Edinbrick 1
Wed 25th July
- Transformed dif F & R DNA into E.coli, incubated at 37C overnight
- designed primers for Sam5 and Sam8 genes (part of vanillin biosynthesis pathway)
Thu 26th July
- Prepared glycerol stock of Pseudomonas fluorescens
- Prepared miniprep of GFP and mint biobricks
- Streaked Pseudomonas fluorescens onto a fresh LB plate
- Revived [http://partsregistry.org/Part:BBa_I0500 BBa_I0500] and [http://partsregistry.org/Part:BBa_Q04510 BBa_Q04510]
Fri 27th July
- Continued miniprep of GFP and mint biobricks
- Restriction digest using SpeI & EccRI restriction enzymes
Monday 30th July
- PCR of fcs and ech genes from Pseudomonas fluorescens was carried out
- when pcr reaction was run on gel there was no product present, therefore we decided to carry out the pcr at a lower annealing temperature
Tuesday 31st July
- Prepared chloramphenicol plate to test if the revived wintergreen biobrick with the duel resistance plasmid was present
- Streaked out glycerol stock of Pseudomonas fluorescenes to determine if viable
- Carried out a second PCR of the ech and fcs genes required for vanillin biosynthesis pathway
- lowered the annealing temperature to 54'C
- extracted DNA from alfalfa leaves ready for PCR amplification of COMT gene required for vanillin biosynthesis pathway
- used the extract and amp kit provided by SIGMA
Wednesday 1st August
- PCR of ech and fcs was run on an agrose gel
- results!! but not what we hoped for
- fcs had several amplified fragments with one being present at the 1700bp mark which could represent the fcs gene
- there was a vague band present at the 800bp mark, which possibly represents the ech gene
- decided to carry out pcr for a third time at a lower annealing temperature to suit the ech gene
- fcs requires a higher annealing temperature to reduce the number of fragments amplifed
- streak plate of Pseudomonas fluorescens showed up positive
- good news means our glycerol stock is viable :)
Thursday 2nd August
- repeated ech PCR at a lower annealing temperature (reduced to 50'C)
- gel showed that there was no improvement in the amplification of the ech gene
- problem could be due to long extention time as ech PCR was ran at same time as a PCR for a larger gene
- PCR of COMT genes required for the vanillin biosynthesis pathway
