One class of inhibitors operate by … WebFenbendazol Informationen >. Wie wirkt Fenbendazol? Fenbendazol wurde ursprünglich entwickelt, um Parasiten zu heilen, indem es selektiv die Synthese von Mikrotubuli durch Bindung an β-Tubulin blockiert. Dadurch wird die Polymerisation von Tubulin-Dimeren in den Zellen der Parasiten gestoppt und der Tod der Parasiten verursacht.

WebTreatment of undifferentiated P19 cells with concentrations of taxol greater than 4 x 10(-8) M caused microtubule bundling and multiple aster formation and promoted polymerization of the low levels of class III beta-tubulin found in these cells. In neurons, at 2 x 10(-8) M taxol, bundling of microtubules at the base of the neurite was apparent. WebTubulin polymerization assay (BK006P) is based on an adaptation of the original method of Shelanski et al. and Lee et al. (1, 2) which demonstrated that light is scattered by microtubules to an extent that is proportional to the concentration of microtubule polymer. solution to new york times crossword no. 0202
