Kinase Assay
For experiments with FAAH, rat liver homogenates, mouse brain homogenates and membranes from COS7 cells transfected with the human enzyme are used. Frozen (?80°C) livers from adult C57BL/6 mice and frozen brains (minus cerebella) from adult Wistar or Sprague-Dawley rats are thawed and homogenized in 20 mM HEPES, 1 mM MgCl2, pH 7. The homogenates are centrifuged at ~35000×g for 20 min at 4°C. After resuspension in buffer followed by recentrifugation and a second resuspension in buffer, the pellets are incubated at 37°C for 15 min. This incubation is undertaken in order to hydrolyse all endogenous FAAH substrates. The homogenates are then centrifuged as above, recentrifuged and resuspended in 50 mM Tris-HCl buffer, pH 7.4, containing 1 mM EDTA and 3 mM MgCl2. The homogenates are then frozen at ?80°C in aliquots until used for assay. FAAH is assayed in the homogenates and in the COS7 cell membranes using 0.5 μM (unless otherwise stated) [3H]AEA labelled in the ethanolamine part of the molecule. Blank values are obtained by the use of buffer rather than homogenate. In the experiments comparing effects of Biochanin A upon FAAH and FAAH-2, the same assay is used but with 16 nM [3H]oleoylethanolamide ([3H]OEA) as substrate and with an incubation phase at room temperature. The choice of OEA rather than AEA for FAAH-2 is motivated by the relative rates of hydrolysis: OEA is metabolized four times faster than AEA by FAAH-2, whereas for FAAH the rate of hydrolysis of OEA is about a third of that for AEA. When 0.5 μM [3H]AEA is used as substrate, assay conditions for rat brain and mouse liver are chosen so that <10% of added substrate is metabolized. For the human FAAH samples, <5% of the [3H]AEA is metabolized in all cases. For 16 nM [3H]OEA, a limited supply of an expensive ligand meant that optimization is not possible, and the amount of substrate utilized is higher (34±1 and 0.5±0.1% for FAAH and its corresponding mock-transfected, respectively; 40±2 and 21±0.4 for FAAH-2 and its corresponding mock-transfected respectively)[1].

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
