Monday
- Completed The Sainsbury Laboratory (TSL) safety induction.- Collected synthesised samples from DNA 2.0 and transformed DNA into E.coli using electrocompetent cells and electroporation. Added 500 μl of Soc broth and incubated for 40 minutes at 37 °C. Spreadplated onto agar plates containing Kanamycin and incubated O/N at 37 °C.
Tuesday
- Selected a single colony from each of the eleven plates and the colonies were grown in TY broth with Kanamycin O/N.- Transformation of pSB1C3 plasmid containing RFP into E.coli using electroporation. Incubated with 50 μl of Soc broth at 37 °C for 1 hour.
- Spreadplated E.coli cells which have been transformed with the pSB1C3 + RFP plasmid.
- Completed calculations for Dig-Lig experiments (Size and conc. of DNA parts calculated,size of acceptor calculated, order of constructs for each reaction determined, dilution and DNA conc. for each reaction determined) Ratio of 2:1, constructs:acceptor (plasmid).
Wednesday
- Midi prep following the Qiagen protocol of the 9 constructs previously synthesised by DNA 2.0 and transformed on Day 2 and DNA conc. of each constrcut determined using the nanodrop. Dig-Lig calculation spread sheet completed using these concentrations.- Set up the first 11 Dig-Lig experiments, placed into PCR block on the slow protocol.
- Carbenicillin plates made and spreadplated with 40 μl of XGAL and 100 μl of IPTG. Plates left to dry upside down in 37°C incubator.
- Transformation of GG DNA into electrocompetent E.coli cells, PROTOCOL:
• Cells removed from -80°C freezer and allowed to thaw.
• A 5 µl sample of DNA was added to a 50 µl aliquot of cells.
• Transfered each 55 µl sample into a cuvette.
• Electroporation pulse on setting ECR1.
• A 500 µl of SOC broth was added to the cuvette.
• A 555 µl cuvette sample was transferred to an eppendorf tube and incubated for 40 min at 37°C.
• A 100 µl sample was spreadplated onto agar plates containing carbenicillin and incubated O/N at 37°C.
- A 20 µl PCR reaction was set up using a GG level 1 acceptor as template DNA containing the primers P1: 0349(PRO+5U) and 0353 (3U+TER) and P2: 0350 (PRO+5U) and 0354 (3U+TER).
- A TBE buffer 1% agarose gel was poured for diagnostic purposes to check the amplification of the PCR products.
- PCR product purification
• Pre-percipitation to remove TAQ polymerase and protein was completed followed by phenolchloroform extraction (x2). Aqueous layer is removed and discarded leaving DNA.
• Precipitation to remove buffer was carried out by adding Na acetate (10%) and ethanol causing the DNA to come out of solution. Aspirator was used to remove buffer, salt and ethanol.
• A salt wash was completed to remove the acetate and ethanol.
• Sample was incubated at 65°C for 2 min to evaporate the ethanol.
Thursday
- Checked Dig-Lig tranformation plates grown O/N and poor blue white selection observed with many blue colonies.- Selected 2 white colonies from each plated and colony PCR performed.
- Following colony PCR, amplified fragments ran on gel to determine size and therefore whether they contained the construct.
- Decided to repeat the 11 Dig-Lig experiments
- Ran digested PCR product from 25.06.2014 on a diagnostic 1% agarose gel in TBE buffer and determined that LacZ had internal restriction enzyme cut sites and product was split into two bands.
Friday
- Found poor blue/white selection on dig-ligs from 26.06.14. Suspected to be due to either the enzyme used or PCR block.- Set up a new set of dig-ligs to test the source of this problem.
