Activity sensor controls

Abstract

An activity sensor sensitive to enzymes indicative of tissue condition are co-administered with control or normalizing activity sensors providing levels of the same enzyme in other tissues or levels of control enzymes indicative of assay success. Levels of control reporters can be used to normalize activity sensor data across samples such as in analyte velocity analyses. Control reporters can also be used to differentiate localized enzyme activity from systemic activity and to confirm activity sensor localization or to troubleshoot activity sensor uptake problems. Activity sensors and controls sensitive to immunological enzymes are particularly useful in assessing immuno-oncology treatments.
