==Protocol== | |||
This protocol was taken from [[User:Matt Hartings/Notebook/AU Biomaterials Design Lab/2014/02/03|Matt Harting's]] notebook | |||
# To a 3-necked flask is added | |||
## 25mL of 20 mM L-cysteine (roughly 22% L-Cysteine) | |||
## 25mL .1459 mM BSA (roughly 78% by mass) | |||
## 5mL of 100mM ZnSO<sub>4</sub> (0.5 mmol) | |||
## 5.437mL of 10.3mM MnCl<sub>2</sub> (0.056 mmol) | |||
## The pH of this mixture is adjusted to 11 with ~1M NaOH (should be on the order of 60uL) | |||
# This mixture is stirred under Ar (I'll use N<sub>2</sub>) for 30 minutes | |||
# 5.505mL of 101mM Na<sub>2</sub>S is quickly added. | |||
# The solution is stirred for 20 minutes | |||
# The solution is then aged at 50C under air for 2 hours. | |||

==Notes== | |||
*In the past we used molar ratios to to relate the ligand to protein ratios, for this specific synthesis method that would have used too large an amount of BSA (approximately 330g) so we instead have started using mass ratios, and this synthesis is the first that we are going to be using it for. | |||
