- The three plates showing new colonies were used to inoculate 5mL TY-medium with amp. (final conc. 100mg/ul).
- The tubes were put in a waterbath at 37C (200 rpm) and grown o.n.
Transporters
Purification of HmtA (PA Q9I147 6xHis Tag)
- SDS-gel electrophosis
- Make a 12% SDS-gel
- Fill gel with samples Wash 1-2 20mM imidazole, Wash1-2 40mM imidazole, Elute1-3 and ladders
- Run 2h at 100V
- Stain the gel in Coomassie blue (2h)
- Destain with demiwater (2x, 10 min microwave)
Vectors
Measure concentration with Nanodrop
DryA lot of time was spent on finding dissociation constants and figuring out how ArsR/D work, and thinking of how to model their interaction. An input function was derived for the ArsR/D operator, but it is not yet completely clear how this should be used in a model (it is a function of the ArsR/D concentration, but at the same time produces ArsR/ArsD). It would probably be better to start with As(III) and derive an input function from that, if at all possible.
