The characteristics of a phospholipid surface are of major importance in the activation of factor X in the presence of tissue factor-factor VIIa (TF-VIIa) complex. A possible tool which provides a measure of the surface corrugation and roughness is the fractal dimension analysis. This paper uses the

โฆ Synopsis
Development of a double exponential model for determining the intrinsic kinetic parameters for factor X activation by tissue factor-factor VIIa (TF:VIIa) complex, during the complete course of the reaction in a flow reactor is described. The model data reveal that the factor X activation rate constant K i gradually increased from 0.0225 to 0.0456 min -i as the shear rate increased from 50 to 3000 sec -i, whereas the factor Xa inhibition rate constant K 2 increased dramatically from 0.307 to 1.09 min -i for a similar increase in shear rate.
