Fibrin gel porosity
WebJul 27, 1989 · In gels formed at high fibrinogen concentrations, or with high amounts of thrombin, the spaces between the fibers decreased, indicating a decrease of gel porosity. The fiber strands were also shorter. Gel porosity decreased dramatically in gels formed at the high ionic strengths. Webgold.f Fibrin fiber diameter and percentage porosity were measured on scanning electron microscopic im-agesg with image analysis software.42,43,h Briefly, analysis (3 transverse images/gel) was performed with the de-fault thresholding algorithm, which highlighted areas of space (no fibers). The analysis was also performed
