Dispersal of the biofilm

Aims:

To perform PCR on the rsn-2(Ranaspumin-2)and lath(Latherin) inserts.

To ligate into a suitable plasmid and transform into competent cells.

To produce successful overnight liquid cultures, then miniprep them.

To perform site directed mutagenesis on lath, thereby removing illegal restriction sites.

To ligate lath into a suitable plasmid and transform it into competent cells.

To produce successful overnight liquid cultures of lath, then miniprep them.

To devise a successful assay of the surfactant proteins.

To digest and ligate the inserts to plasmids with ribosome binding sites, the three light-dependent promoters, and double terminators present.

To characterise the latherin and ranaspumin constructs, by testing them in a biofilm setting.

To ligate the inserts into the submission vector and submit them to the registry.

Methods:

The DNA of Latherin and Ranaspumin-2 we obtained was in plasmids. In both cases, there were two versions of the genes: one containing HIS tag and on without it. The coding sequences were excised from the plasmids and the Standard BioBricks end were added through PCR. Additionally, Latherin contained three illegal restriction sites. Therefore, we had to perform Site Directed Mutagenesis (SDM) to eliminate them. Table 1 contains the primers we used to achieve that.
