Phosphotase, Ligation and Transformation of LuxPQ into BBK vector
Purpose: to construct and transform the LuxPQ insert and psB1AC3 insert in order to standardize the genetic part for future construction. The products from the overnight digest (July 1) underwent phosphotase treatment and subsequent ligation and transformation into TOP10 competent cells. The cells were then plated on LB+chlor plates.

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.
