Continuation of the research in Antifreeze proteins
Usefulness of the signalling system in antifreeze activity
For example, when cryopreserving a tissue, you want to have a uniform level of antifreeze activity across the tissue; thus if you integrate the bacteria with AI2 signalling system to produce these antifreeze proteins all at once, then you would have a better chance of spreading the antifreeze protein across the tissue.

Repeat of colony PCR of J13002 + LuxOD47A + B0015
The purpose and materials/methods are the same as they were yesterday. This time, only 4 colonies were tested, along with the same size controls as yesterday.
Results:
The 1% agarose gel is shown below. Lanes 1 and 15 are a GeneElute 1kb+ DNA ladder; lanes 2-5 are 4 different colonies of the recently-PCR'd samples (2uL of PCR product); lanes 9-12 are those same colonies but with only 1uL of PCR product; lanes 6 and 8 are 2 different colonies of LuxOD47A + B0015 as a size control; lane 7 is LuxOD47A BBk as a further size control; and lanes 13 and 14 are both negative controls.
Plasmid isolation and NotI restriction digest
Purpose: To further verify if the J13002 + LuxOD47A + B0015 was successfully biobricked into the colonies.
Materials and methods:
These were done in accordance with the procedure outlined on the protocol page.
Results:
These are attached below. Colonies 1 and 5 are encouraging, and were sent down for sequencing later today.
