Micro nucleus test
AutoMN for automated micro-nucleus scoring in cytokinesis-blocked lymphocytes, providing a reliable, sensitive, specific (95%) method as an early predictive marker for cancer risk, and assessment of DNA damage in oncology genetic instability.
The software algorithms were designed for MN test scoring in standardized preparations for various cell types (human lymphocytes, buccal cells, L51178Y, V79, CHL, CHO, TK6, HepG2…) and staining techniques. The detected damaged cells can be “Reviewed and Validated” by the expert, using a simple and flexible interface.
Algorithms also available for recognition of other cytogenetic events, e.g., nucleo-plasmic bridges, nuclear buds, necrotic, apoptotic cells, allowing automation of a comprehensive Cytome analysis system.

Comet assay
AutoComet for automated scoring by detection of thousands of comets of a well-established method of single-cell electrophoresis gel to assess a broad spectrum of DNA damage, with high sensitivity, widely used in regulatory, biomonitoring studies at large scale. recognized as the reference system by blue chip customers and Centers of Disease Control.
This approach provides an operator-independent, accurate quantification of DNA damage and repair in large smart data related to cancer human

Chromosome Aberration Scoring (CAS) and Sister Chromatid Exchange (SCE)
CAS and SCE scoring benefit from the Metafind module for automated fast metaphase finder and from KARYO module for automated and interactive karyotyping.
The list of aberrations can be customized to users’ needs, stored in the database with reports and all samples’ images and data.
Protein Level Expression of H2AX
This module provides automated high-throughput screening of samples in any format (e.g., smear on pattern-slides, cell-on-chip) for quantitative evaluation of histone phosphorylation after radiation.
