Tartrate inhibits which ACP source?

Explanation:
Tartrate inhibition distinguishes acid phosphatase isoenzymes by their tartrate sensitivity. The non-prostatic ACP sources (bone, red blood cells, and liver) are tartrate-sensitive and are inhibited by tartrate. Prostatic acid phosphatase is tartrate-resistant, so its activity remains in the presence of tartrate. This is why tartrate is used to suppress non-prostatic ACPs when selectively measuring prostatic ACP. So tartrate inhibits RBC, bone, and liver ACP, but not the prostatic form.
