Reducing the Use of Animals in Safety Testing: Strategic Roadmap Released

February 1, 2018
The National Toxicology Program, in collaboration with other US federal agencies, has published a strategic roadmap offering a new framework for the safety testing of drugs & chemicals aimed at reducing the use of animals. Read more....

Video: Bovine Corneal Opacity & Permeability Test – Spanish

October 16, 2017
This 13- minute training video demonstrates how to perform the BCOP assay according to the Test Guidelines set forth for the assay by the Organization for Economic Co-operation and Development (OECD TG 437). The video focuses on steps that are critical to the success of the assay such as handling of the isolated cornea and removal of the test material from the cornea at the conclusion of the exposure time. ...

Quality Considerations: Redefining Test Systems from Animals to Tissues and Beyond

August 28, 2017
The use of non-whole animal test methods transforms the way regulatory requirements are applied in preclinical testing. Recent global regulatory initiatives emphasize the importance of transitioning to human relevant assays and test systems that do not use animals. When these methods are moved from research into the regulated arena, GLP principles must be followed. The GLPs were originally written in the 1970s, when the vast majority of regulated research was performed using animals as the test system. Current innovative, alternative...

Video: The 3T3 Neutral Red Uptake Phototoxicity Test — Chinese

November 21, 2016
This training video with Chinese subtitles explores a cell-based method for assessing Phototoxicity — or the potential for chemicals to cause damage after being exposed to light. The method is used widely around the world by many industries, including the cosmetics and pharmaceutical sectors. Disclaimer: Please note that the procedures shown in this video were for demonstration purposes only and that all assay procedures, except the UVA/dark exposure, should be performed in a biological safety cabinet using aseptic techniques. Due to...

Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology

October 18, 2016
This 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, 2016
The 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...

Eye Irritation Test (EIT, OECD 492)

August 24, 2016
The Eye Irritation Test (EIT) is an OECD-approved in vitro non-animal test method for identifying chemicals and mixtures that may be irritating to the corneal epithelium.  The test method utilizes an in vitro reconstructed human corneal epithelium (RhCE) model (EpiOcular™, MatTek Corp. or HCE, SkinEthic), in an acute exposure assay to support international regulatory labeling requirements, according to the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS). The Eye Irritation Test can be used to support...

Bovine Corneal Opacity and Permeability (BCOP, OECD 437) with Optional Histology

August 24, 2016
The 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...

Eye Irritation Time-to-Toxicity

August 24, 2016
The ocular irritation potential of formulations, products, ingredients, and chemicals can be evaluated using in vitro reconstructed human corneal epithelium (RhCE) models, such as the EpiOcular™ (MatTek Corp.) and SkinEthic HCE (EPISKIN) organotypic 3-D tissue constructs.  Whether evaluating ultra-mild cosmetics and personal care products, or rank ordering the irritation potential of candidate formulations and ingredients, we can provide custom Ocular Screening protocols to best meet your testing goals. The Ocular Screening protocols use a time-to-toxicity procedure to determine the test material...
