Flutax-2 (5/6-mixture)（Cat No.:I045860）is a fluorescent taxol derivative composed of a mixture of 5- and 6-carboxyfluorescein-labeled paclitaxel conjugates. It binds specifically to microtubules, stabilizing their structure while providing a fluorescent signal for visualization. This dual functionality makes Flutax-2 an important probe in cell biology, enabling real-time imaging of microtubule dynamics, drug binding, and intracellular distribution. Researchers commonly use it to study mechanisms of mitosis, cytoskeletal organization, and the effects of tubulin-targeting agents. The 5/6 mixture ensures broad utility in fluorescence-based assays and microscopy applications.
