Protocols
Here's the techniques we used blah blah blah"
Preparation of CaCl2 Competent Cells
A good supply of shortbread is essential to any productive lab environment.
- Dilute 400μl of overnight liquid culture into 20ml of broth with any necessary antibiotics to select for any plasmids already transformed into the cells
- Incubate at 37⁰C, shaking at 225rpm for 90 minutes
- Spin down for 2 minutes at 7000rpm at 4⁰C
- Discard supernatant, resuspend pellet in 10ml of 50 mM CaCl2, keep on ice
- Repeat centrifugation for 2 minutes at 7000rpm at 4⁰C
- Discard supernatant and the resuspend pellet in 1ml of 50 mM CaCl2, keep on ice
- CaCl2 competent cells can be kept on ice in the fridge overnight
Shortbread
A good supply of shortbread is essential to any productive lab environment.
- Heat the oven to 190C/375F/Gas 5
- Beat the butter and the sugar together until smooth.
- Stir in the flour to get a smooth paste. Turn on to a work surface and gently roll out until the paste is 1cm/½in thick.
- Cut into rounds or fingers and place onto a baking tray. Sprinkle with caster sugar and chill in the fridge for 20 minutes.
- Bake in the oven for 15-20 minutes, or until pale golden-brown. Set aside to cool on a wire rack.
