Applications of BBa_K638202
The purified his-tagged Reflectin A1 has optical properties, best viewed when made into a thin film. The original method for making reflectin thin films was developed by [http://www.nature.com/nmat/journal/v6/n7/full/nmat1930.html Kramer et al, 2007.], and then [http://2011.igem.org/Team:Cambridge/Experiments/Thin_Films repeated and modified by the Cambridge iGEM Team 2011].
First the protein must be dissolved in an ionic solvent such as [http://en.wikipedia.org/wiki/Hexafluoro-2-propanol HFIP] (hazardous - use in a fume hood) and then can be coated onto a highly clean smooth substrate. Silicon Wafers and glass microscope slides have been shown to work. A razorblade can be used to scrape across a single drop to form a thin film, but more uniform results can be achieved with the use of a [http://2011.igem.org/Team:Cambridge#/Protocols/Flow_coating flow coater] or a [http://2011.igem.org/Team:Cambridge#/Protocols/Spin_Coating spin coater device].
