New for iGEM 2010 is the ''groupparts'' tag.  This tag will generate a table with all of the parts that your team adds to your team sandbox.  Note that if you want to document a part you need to document it on the [http://partsregistry.org Registry], not on your team wiki.

Reflectins are a family of proteins which help give cephalopods their amazing camouflage abilities and which can self-assemble into a variety of multilayered structures with optical properties. We worked with Reflectin A1 from Loligo pealeii. See our [[Team:Cambridge/Project/Background | background page]] for more information about reflectins and their role in cephalopod camouflage.

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K638001 Reflectin A1]

Reflectins are a family of proteins which help give cephalopods their amazing camouflage abilities and which can self-assemble into a variety of multilayered structures with optical properties. We worked with Reflectin A1 from Loligo pealeii. See our background page for more information about reflectins and their role in cephalopod camouflage.

In order to isolate pure reflectin, we built and submitted [http://partsregistry.org/wiki/index.php?title=Part:BBa_K638202 Poly-His tagged Reflectin A1 generator]. In pure form reflectins may be used to create vibrantly coloured thin films and other devices. We used a poly-His affinity column to purify reflectin from cells for this purpose.

E. coli transformed with our pBAD-ReflectinA1-GFP construct

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K638301 Reflectin A1 GFP fusion]

This BioBrick was created in order for us to control for the expression of reflectin and its location in the cell. Using it, we were able to determine that reflectin forms inclusion bodies when expressed at a high level.

[http://partsregistry.org/wiki/index.php?title=Part:BBa_K638402 Improved TorA tag]

We submitted a variant of the TorA leader sequence export tag. This TorA leader sequence variant has had been successfully used to export GFP to the periplasm of E.coli as described [http://www.ncbi.nlm.nih.gov/pubmed/11123687 here]. Our tag differs slightly from [http://partsregistry.org/wiki/index.php?title=Part:BBa_K233307 the TorA tag already in the registry] and should be cheaper to obtain from primer synthesis.
We also submitted [http://partsregistry.org/wiki/index.php?title=Part:BBa_K638401 Reflectin A1 with N-terminal TorA tag] and [http://partsregistry.org/wiki/index.php?title=Part:BBa_K638403 Reflectin A1 with N-terminal TorA tag and C-terminal sfGFP], which we used in our periplasm export attempt.

...and the rest
