Finally, you want to make completely certain that you purified the correct protein and not some other protein (like biochemisnotfunase). To confirm the identity of your protein, you run a Western blot. When doing a Western, one typically needs a solution of phosphate-buffered saline, which is comprised of 10 mM phosphate buffer (pH 8.0) and 0.9% (w/v) NaCl. Describe how you would make 500 mL of this solution including the grams of sodium phosphate, monobasic and sodium phosphate, dibasic that you would need.

Question

Finally, you want to make completely certain that you purified the correct protein and not some other protein (like biochemisnotfunase). To confirm the identity of your protein, you run a Western blot. When doing a Western, one typically needs a solution of phosphate-buffered saline, which is comprised of 10 mM phosphate buffer
(pH 8.0) and 0.9% (w/v) NaCl. Describe how you would make 500 mL of this solution including the grams of sodium phosphate, monobasic and sodium phosphate, dibasic that you would need.

Making the phosphate buffer is a little tricky. Be sure to use the correct ratio of monobasic and dibasic sodium phosphate to get the correct pH. The Henderson- Hasselbalch equation might come in handy here. Finally, the molecular weight of sodium phosphate, monobasic (NaH2PO4) is 119.98 g/mol and the molecular weight of sodium phosphate, dibasic (Na2HPO4) is 141.96 g/mol.
