Abstract
Summary
The present study has revealed that 45% of acid phosphatase in rat poly-morphonuclear leucocytes can be recovered from the granular fraction, 21% from the nuclear fraction, and 34% from the supernatant fraction. Acid phosphatase in the granule fraction appeared to have properties distinctly different from those of the enzyme in the nuclear and soluble fractions. The enzyme in the granule fraction was more stable, possessed a lower pH optimum, and was preferentially inhibited by sodium fluoride.
