| '''Preparation of 500 mM ADP stock solution''' (dissolved in H<sub>2</sub>O):
| |
|
| |
| ::1) weigh 491.2 mg of ADP (1 mmol ADP)
| |
| ::2) add 1.3 ml H<sub>2</sub>OΒ !White precipitate will occur, which will be dissolved after 1-2 min of stirring on magnetic stirrer at room temperature!
| |
| ::3) neutralize with 5 N KOH (approx. 465 Β΅l)Β !ADP will dissolve after addition of KOH!Β (this is '''Solution A''')
| |
| ::4) check pH and adjust to 7 if necessary
| |
| ::5) adjust final volume to 2 ml and divide into 0.2 ml portions
| |
| ::6) store frozen at -80 Β°C

| '''Preparation of 500 mM ADP stock solution with 3 mM free Mg<sup>2+</sup>''':
| |
|
| |
| To keep free [MgMg<sup>2+</sup>] constant during respiration measurement mix ADP (or ATP) with MgCl<sub>2</sub> (0.6 mol/mol ADP or 0.8 mol/mol ATP).
| |
|
| |
| '''MgCl<sub>2</sub>''' (Scharlau MA0036: MgCl<sub>2</sub>.6H<sub>2</sub>O, FW = 203.3)
| |
|
| |
| ::1) add 121,98 mg MgCl<sub>2</sub> to '''Solution A'''
| |
| ::2) follow steps 4-6 of the above instructions

| '''Oxygraph-2k Manual Titrations:'''Β [[MiPNet09.12]]
| |
|
| |
| ::* Titration volume: 8-20 Β΅l using a 25 Β΅l syringe
| |
| ::* Final conc. in 2 ml O2k-chamber: 2-5 mM
