ACT + requires a sample [greater than]20 times smaller than that required for a celite
or kaolin ACT.
Nonetheless, based on his comparison with four direct testosterone immunoassay methods, Stanczyk proposes that a RIA, rehabilitated with organic solvent extraction and Celite
column partition chromatography, could be used as a "gold standard" (4).
The reaction mixture was filtered over a short column packed with celite
for 7 hr and evaporated in vacuc to afford the crude oil (725 mg) which was subjected to CC on silica gel with n-hexane-EtOAc gradient, followed by recrystallization from EtOAc/n-hexane to give 5,6-dehydrokawain (1) as colorless needles (245 mg; 82.
The sample volume and the amount of internal standard were adjusted according to the testosterone concentration measured previously by extraction-partition celite
chromatography/ RIA (25) to obtain a ratio of unlabeled/ labeled testosterone between 0.

The pigs were fed for a period of 4 weeks during which, from day 10 to 14 and day 24 to 28, Celite
, a source of acid insoluble ash (AIA), was added to all diets at 20 g/kg feed as an indigestible dietary marker.

This system allows estimation of patient-specific anticoagulant response to heparin, determination of Celite
ACT values, and calculation of protamine dose by ACT-based approximations of heparin concentration (protamine response test).
