I recall (from the 90's) that the cardiac version has a half-life of around 4 days but I'm not sure how it relates to the intestinal version. You should do a few literature surveys to find the information; I imagine someone must have already done the measurements by now..

Dear Tausif

Thank you very much for your reply. Unfortunately there is not solid data on literature focusing on kinetic of IFABP. By the way, I do appreciate your time.
