Principle
In acidic pH of the buffer system, Acid Phosphatase hydrolyses a-naphthyl phosphate to a-naphthol and phosphate. The o-naphthol is then coupled with Diazotized Fast Red TR to form a Diazo dye which has strong absorbance at 405 nm. The increase in absorbance is directly proportional to the level of acid phosphatase in serum.
The addition of L-Tartrate inhibits prostatic acid phosphatase but does not inhibit other isoenzymes.
The activity of Prostatic Acid Phosphatase is obtained by subtracting the result of Non prostatic Acid phosphatase (Determination with Tartrate) from Total Acid Phosphatase (without tartrate).

Quality Control
To ensure adequate quality control it is recommended that each batch should include a normal and an abnormal commercial reference control serum. It should be realized that the use of quality control material checks both instrument and reagent functions together. Factors which might affect
ne performance of this test includes proper instrument function, temperature control, cleanliness of glassware and accuracy of pipetting.
Other Details
The kit should be stored at 2-8 °C and is stable till the expiry date indicated on the label.
The working solutions of —- Non Prostatic Acid Phosphatase & Total Acid Phosphatases are stable for 7 days at 2-8 °C.
