ETL is a research, development and testing laboratory concentrating its efforts on new approaches to toxicity testing. ETL has developed and recently patented a simple, rapid and cost-effective cytotoxicity screen, the Tetramitus Assay.

This exciting new test, which measures growth inhibition in the flagellate Tetramitus as an indicator of cytotoxicity, can detect the presence of toxic agents in a variety of biological samples. The Tetramitus Assay has numerous advantages over its competitors and has a wide range of applications.

ETL Conducts Tetramitus Particle Toxicity Tests on the EPA Reference Toxicants used in the Mouse WTC Inhalation Study ETL has performed Tetramitus Particle Toxicity Tests on diesel particle exhaust and the three reference toxicants used in the EPA study.
