==Calculation of reagents for ADA kinetic assay==
 
-
* It was decided to prepare a 30 mM stock solution of adenosine. The calculation below shows the amount needed to obtain 30 mM of adenosine.
 
-
 
-
.030  <math>\frac{mol}{L}</math> mol of adenosine × <math>\frac{267.24  g}{1  mol}</math> = <math>\frac{8.0172 g}{L}</math> × .010 L = 0.0802 g of adenosine

The calculation of for the buffer was formulated by [[User:Catherine Koenigsknecht/Notebook/Experimental Biological Chemistry/2013/01/23|Catherine Koenigsknecht]]

* Procedure: Buffer
 
-
#Protocol for 0.1 M Sodium Phosphate Buffer (pH 7.4)
 
-
#Add 3.1 g of NaH2PO4•H2O and 10.9 g of Na2HPO4 (anhydrous) to distilled H2O to make a volume of 1 L. The pH of the final solution will be 7.4. This buffer can be stored for up to 1 mo at 4°C.
 
-
#Dilute to 0.05M: (take 50 mL of 1M solution and dilute in 1 Liter H2O)
