RAMONA
We built Ramona to advance human health through live imaging that delivers unrivaled precision and scale

Our goals


The potential of novobiocin, recently identified to be a DNA POLѲ inhibitor, to augment cancer chemotherapy was explored in the late 1980s and early 1990s in tumor cells, tumor-bearing mice and in Phase 1 clinical trial in combination with cyclophosphamide or cisplatin. Genetic alterations which may increase or decrease POLѲ inhibitor effects have been elucidated. Thirty patient-derived tumor cell lines with known BRCA, ATM, ATR, POLѲ, XRCC1, PALB2, PARP1, LIG3 alterations as well as know gLOH% and MSI status were screened in a mct-spheroid assay (tumor cells, endothelial cells, mesenchymal stem cells) with a POLѲ inhibitor, novobiocin, ART-558, and RP6685, alone or in simultaneous combination with a FDA-approved or investigational anticancer small molecule with a 7-day exposure and a CellTiter-Glo 3D luminescence endpoint.
Convulsive seizure behaviors are a hallmark feature of epilepsy, but automated detection of these events in freely moving animals is difficult. Here, we employed the Ramona Kestrel™, a high-resolution multi-camera array microscope with high-speed video acquisition and custom supervised machine learning (ML) for automated detection of larval zebrafish between 3- and 7-days post-fertilization (dpf). We assessed data from over 2700 zebrafish either exposed to a chemoconvulsant (pentylenetetrazole, PTZ) or genetic zebrafish lines representing Developmental Epileptic Encephalopathy (DEE) syndromes.
This paper presents a validation of the Ramona Kestrel™ for automated, high-throughput screening for early-stage drug development and toxicology assessment with zebrafish embryos. The Kestrel™ is a novel high-throughput imaging platform featuring a 24-camera array that enables simultaneous acquisition of high-resolution video data across 96-well plates. This paper validated the system using zebrafish embryonic photomotor response (EPR) assays, demonstrating its ability to track behavioral responses in chorionated and dechorionated embryos without workflow modifications. The system successfully detected concentration-dependent responses to ethanol, methanol, and bisphenol A across different plate formats and well volumes
