Abstract: The present disclosure relates to materials and methods for live imaging of biological samples. In particular, the present invention provides antibody fragments for purposes of detecting (e.g., visualizing, monitoring, measuring, evaluating, and/or analyzing) cellular activity within biological samples (e.g., live tissue samples, live cell samples). In some aspects, the disclosure relates to use of antibody fragments (e.g., camelid antibody fragments) for detecting and measuring a response to an immunotherapy in live cells (e.g., live tumor fragments).

Abstract: Provided are ex vivo systems and methods of predicting the response of a drug or other agent on a tissue. In some embodiments, the systems and methods comprise cutting a tissue into tissue fragments, adding a drug or other agent to the tissue fragments based on an estimated tumor content, and performing an ex vivo measurement on the tissue fragments.
