Since 1993 Cytoskeleton has provided purified tubulin proteins to the scientific community. We continually strive to provide the purest, most biological active and relevant tubulin proteins, kits and reagents for today's researchers. The kits are designed to enhance the productivity ot the time you have available for research, usually saving months of development time. Kits range from the basic tubulin protein and buffers version, BK015, to the Microtubule Binding Assay, BK029, and the polymerization assays described below. We also provide a kit for measuring the ratio of microtubules to subunit tubulin in cell extracts BK038. Detailed information can be found by clicking on the links below.
