Fig. 3From: Mechanical fibrinogen-depletion supports heparin-free mesenchymal stem cell propagation in human platelet lysateQuantitative ELISA reveals efficient depletion of fibrinogen. Quantitative ELISA demonstrated that fibrinogen concentration in depleted media B and C is 1000-fold lower compared to standard medium A. Data shown are mean values of three independent medium preparations measured in quadruplicates ± standard deviation (SD). The significance level is indicated by asterisks (* p < 0.001)Back to article page
