Aliquots drawn at different time intervals (2 and 24 h) were centrifuged for 30 min at 7500 rpm to separate the particles and aggregates.
Further, 5 mL blood samples were drawn at different time intervals at 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5.05.0 and 6.0 hr into tubes containing 0.5 ml of 2% EDTA solution to prevent blood coagulation.
Aliquots of the reaction mixture were drawn at different time intervals and kept for 1 h at 37°C in the presence of 0.3 mM N- ethoxycarbonyl -2-ethoxy-1,2-dihydroquinoline (EEDQ) coupliN- ethoxycarbonyl -2-ethoxy-1,2-dihydroquinoline DMSO.
The Rf values of the samples drawn at different time intervals were exactly matching with standards of 3-NC and 3-MC.
Most of them recommend use of glucose challenge tests, wherein pregnant women are subjected to an oral glucose solution and blood samples are drawn at different time intervals; except the American Diabetes Association ADAA) which prior to 2010 recommended a non-challenge test.
Samples were drawn at different intervals and analyzed for residual BA.
For the determination of the adenine serum concentration, in one rat, blood samples were drawn from a carotis canula at different time intervals (5, 15, 25, 40, 55 and 70 min after the bolus adenine injection).
