Activity of adenosine deaminase allelic forms in intact erythrocytes and in lymphocytes

Abstract
SUMMARY: The distribution of ADA activity has been studied for ADA 1 and ADA 2‐1 individuals in intact and lysed erythrocytes and in lymphocyte lysates.ADA activity in intact RBC is 20‐30% lower than in lysates, in lymphocytes it is 10 times higher.The difference between ADA 1 and ADA 2‐1 mean enzyme activities which we previously described in RBC lysates has been found also in intact RBC and in lymphocyte lysates.
