Synechocystis medium

Recipe
{{{tech}}}

To grow Synechocystis cultures, BG-11 medium was made according to the recipe found on the PhotoSynLab wiki.

Gibson Assembly

{{{tech}}}

The Gibson assembly protocol can be found at New England Biolabs.

DNA isolation and cleaning

{{{tech}}}

For plasmid isolation, the Promega Wizard Plus SV Minipreps DNA Purification System A1460 Miniprep protocol was used. For PCR product isolation, the QIAquick PCR Purification kit was used.

DNA digestion

{{{tech}}}

DNA digests for both ligation and verification used the protocol in the PhotoSynLab wiki.

PCR

{{{tech}}}

The touchdown PCR procedure detailed on the PhotoSynLab wiki was used to amplify DNA.

Nanodrop

{{{tech}}}

A NanoDrop ND-1000 Spectrophotometer was used to determine DNA concentrations.

3A assembly

{{{tech}}}

3A assembly was conducted according to the iGEM 3A assembly protocol.

Ligation

{{{tech}}}

Ligation was performed according to the protocol outlined on the PhotoSynLab wiki.

Transformation (Escherichia coli)

{{{tech}}}

The protocols used for preparing competent DH5a cells, as well as the heat-shock transformation procedure employed can be found at the PhotoSynLab wiki.

Transformation (Synechocystis sp. PCC 6803)

{{{tech}}}

The transformation procedure for transforming Synechocystis can be found at the PhotoSynLab wiki.
