Abstract: | A variety of biochemical fractionation methods are available for the quantification of cytoskeletal components. However, each method is designed to target only one cytoskeletal network, either the micro tubule (MT) or actin cytoskeleton, and non-targeted cytoskeletal networks are ignored. Considering the importance of MT actin crosstalk, the organization of both the targeted and non-targeted cytoskeletal networks must be retained intact during fractionation for the accurate analysis of cytoskeletal organization. In this study, we reveal that existing fractionation methods, represented by the MT sedimentation-method for MTs and the Triton X-100 solubility assay-method for actin cytoskeletons, disrupt the organizations of the non-targeted cytoskeletons. We demonstrate a novel fractionation method for the accurate analysis of the cytoskeletal organizations using a taxol-containing PEM-based permeabilization buffer, which we name "semi-retentive cytoskeletal fractionation (SERCYF)-method". The organizations of both MTs and actin cytoskeletons were retained intact even after permeabilization with this buffer. By using the SERCYF-method, we analyzed the effects of nocodazole on the cytoskeletal organizations biochemically and showed promotion of the actin cytoskeletal organization by MT depolymerization.
