Strategies for Eye Irritation Testing
September 17, 2018Determination of ocular irritation potential is a key toxicological endpoint required to support chemical and raw material characterization and industrial hygiene, to guide product development, and to achieve final product safety standards. IIVS possesses extensive experience with numerous test methods and testing strategies for commercial, industrial and regulatory applications. From standard regulatory hazard assessments to providing information on the degree of ocular irritation, to discriminating among extremely mild eye area products, IIVS’ Study Directors take the time to understand your...
Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology
October 18, 2016This one-hour webinar, led by IIVS Director of Quality and Compliance, introduces some of the concepts of Good Laboratory Practices (GLPs) designed to promote study and data integrity within an in vitro toxicology framework. Applying these concepts within your own laboratory should aid in production of robust, repeatable studies. View Slides...
Short Time Exposure (STE, OECD 491)
August 24, 2016The Short Time Exposure (STE) assay, developed by Kao Corporation (Japan), is an in vitro assay used to assess acute eye irritation potential as an alternative to the traditional in vivo Draize test. The test method evaluates the cytotoxicity induced by a series of test chemical dilutions in a monolayer of rabbit corneal fibroblasts (Statens Seruminstitut Rabbit Cornea – SIRC) after a single five-minute exposure. Two prediction models were initially developed for the STE assay — one categorizes the test material as...
Bovine Corneal Opacity and Permeability (BCOP, OECD 437) with Optional Histology
August 24, 2016The BCOP (Bovine Corneal Opacity and Permeability) assay is an in vitro eye irritation test method developed by Gautheron et al. (1992), which uses living bovine corneal tissue, obtained as a by-product from abattoirs, to evaluate the potential ocular irritancy of a test article. Types of injury caused by exposure to the test article are quantitatively measured by changes in opacity and permeability to fluorescein. The BCOP assay allows for the investigation of the mechanism of the damage caused. Corneal opacity...
