Abstract
Tumor Treating Fields (TTFields) are an FDA-approved anticancer treatment using alternating electric fields. Here, we present a protocol to perform live-cell imaging (LCI) of cells during TTFields treatment with the Inovitro LiveTM system. The setup we describe dissipates TTFields-related heat production and can be used in conjunction with any LCI-compatible microscope setup. This approach will enable further elucidation of TTFields' mechanism of action at the molecular level and facilitate the development of promising combination strategies.
