TAT-complex levels in mouse plasma after two different blood drawing techniques, determined with the home made TAT assay. Plasma samples were obtained by either collection of venous blood in a syringe filled with 180 μl 3.2 %(w/v) citrate (Citrate in Syringe) or by i.v. injection of 3.2% (w/v) sodium citrate (body weight (gr) / 13 × 10 μl) into the vena cave 20–30 seconds before blood drawing (Citrate in Vein).
