動的微小管および関連タンパク質をイメージングするための同時干渉反射および全内部反射蛍光顕微鏡

Executive Industry Relevance

Simultaneous IRM and TIRF microscopy enables high-speed, dual-channel imaging of dynamic microtubules and associated proteins without the need for extensive labeling or complex optical setups. This capability supports early-stage target validation and mechanistic de-risking by providing quantitative, label-free visualization alongside single-molecule fluorescence detection. The approach streamlines imaging workflows, reduces photobleaching risk, and enhances predictive confidence in cytoskeletal protein studies relevant to biopharma discovery pipelines.
