Preparation of IPTG and Chloramphenicol plates

• The IPTG/Chloramphenicol plates that were prepared earlier on (08/08/13) for the volatile organic compound (VOC) test were found to be contaminated.
• Hence new plates had to be made using the below protocol;

PROTOCOL:

• x2 400ml of already prepared and sterilized agar was obtained from the media kitchen.
• The agar was microwaved using the lowest power level at 2-3 mins intervals until completely melted.
• The x2 400ml agar were then placed in the 37 degrees room to cool.
• After cooling, 800ul of cholramphenicol and 400ul of IPTG were added to one bottle whilst only 800ul of chloramphenicol was added to the second bottle.
• The contents of both agar bottles was then poured into ...

Ligation of PCR products (TOD operon) using the Promega pGEM-T Vector System

The samples ligated were A (TODX), C (TODF) and E (TOBG)

The promega protocol was followed and it can be found at http://www.promega.co.uk/resources/protocols/technical-manuals/0/pgem-t-and-pgem-t-easy-vector-systems-protocol/

To calculate the amount of DNA insert needed for each sample, we used the promega biomath calculator (www.promega.com/biomath). We used the 1:3 ratio of DNA.

• Volume of DNA insert for each sample
  • A - 1.6ul
  • C - 1.1ul
  • E - 1.ul
