1.0 ml of horse radish
              peroxidase homogenate
              has an Absorbance-A595 of 0.55

  1.0 ml = 7.143 mg of albumin equivalent

  1,400 ml =  7.143 x 1,400 = 10,000mg
         albumin  protein equivalent


   1.0 ml converts 71.43 uMoles
                              of H2O2 to H2O per min

   thus 7.143 mg protein converts
                              71.43 uMol to product and 

   71.43 / 7.143 gives 10 Int'l Units
                              of enzyme activity per mg

             10,000 mg protein = 100,000 IU

                      (1 I.U. is 1 uMole/min)
