1M KPO4
Buffer
To make a 1M Phosphate buffer (KPO4, pH 8.5-8.7) combine:
9.5 mL 1M K2HPO4 and 0.5 ml 1M KH2PO4
Phosphate wash buffer
Buffer
For 100 mL Phosphate wash buffer (5 mM KPO4, pH 8.0, 80% EtOH) mix: 0.5 ml 1 M KPO4 pH 8.5 + 15.25 mL MilliQ water + 84.25 mL 95% ethanol. Wash buffer will be slightly cloudy.
** IMPORTANT: Phosphate wash buffer should be prepared daily.
Phosphate elution buffer
Buffer
Diluting 1 M KPO4, pH 8.5 to 4 mM with sterile water
Sodium Carbonate Buffer
(Na2CO3): 0.5M, pH 9.0. Dissolve 4.2 g NaHCO3 in 80 mL of sterile water and adjust pH to 9.0 with 10 N NaOH; bring volume up to 100 mL with sterile water. To make a 50 mM solution for the dye coupling reaction dilute 1:10 with water.
Note: Carbonate buffer changes composition over time; make it fresh every couple of weeks to a month.
