Cytotoxicity Assay Analyzer

Purpose

The Cytotoxicity Assay Analyzer skill provides comprehensive in vitro toxicity assessment of nanomaterials, enabling systematic evaluation of cell viability, determination of safe exposure levels, and identification of toxicity mechanisms.

Capabilities

MTT/MTS/WST assay analysis
Live/dead staining quantification
IC50/EC50 calculation
Dose-response curve fitting
Cell morphology analysis
Apoptosis/necrosis detection

Usage Guidelines
