WebSimilarly, several publications have reported the stiffness values for Collagen I gels. Using a rotational rheometer, stiffness of Collagen I (rat tail, 2 mg/mL) was reported to be 9 Pa23. Furthermore, when Collagen I was mixed with Matrigel matrix at a concentration of either 2 or 4 mg/mL, the stiffness increased to 13.4 and 40.7 Pa, respectively. Web1. jún 2010 · Collagen is a semi-flexible polymer. Therefore its persistence length (P L) and Young's (elastic) modulus (E) can be used to characterize its mechanical properties. While E is a measure of the stiffness of an isotropic elastic material, P L is a particularly useful quantity for assessing mechanical properties of biopolymers.

WebWe used an analytical approach to determine the persistence length (P(L)) of collagen fibers from transmission electron microscope images of immobilized collagen. Fluctuations in the curvature of collagen fibers formed in-vitro (with or without recombinant DDR2) were analyzed to ascertain their P(L). WebThe persistence length quantifies the stiffness of long polymer chains, making it an appropriate parameter for estimating collagen stiffness. ... but it should be noted that the …
