To make 0.5M TCEP aliquots

This is just dissolving the TCEP and pH-ing back to 7.0

 

1)      Pour 6 x 1g bottles of TCEP powder into a 50ml conical.

2)      Fill one of the TCEP bottles with cold H2O and pour from one to the other to collect all the powder that was left behind, then pour into the 50mL conical.

3)      Add cold water to ~35mL.

4)      Add KOH pellets to pH to 7.0.  This means adding around 45 pellets, so add ~40, rock until dissolved, then add one by one dissolving 'till the pH is 7.0

5)      Make up to 40mL with cold H2O.

6)      Aliquot in 1mL ependorfs, and freeze at -20ēC.
