IIVS at SOT 2018

February 8, 2018
IIVS will have several events and posters at the upcoming SOT meeting, March 11-15, in San Antonio, TX.  The events and three of our five posters focus on our respiratory toxicology program in support of our new laboratory that opened in 2017.  Other posters examine topics in phototoxicity.  Be sure to visit our booth at the meeting - Booth #533.   View more details on our events and posters at SOT....

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...

Non-Animal Testing Approach to Address Biocompatibility Testing of Medical Devices Required by the United States Food and Drug Administration (US FDA)

August 28, 2017
Presented at the 2017 World Congress on Alternatives and Animals in the Life Sciences (WC10) E. Hill, R. Curren, and G.-E. Costin Starting in December 2015, personal lubricants must receive pre-market approval from the US FDA Center for Devices and Radiological Health (CDRH) in order to be sold in the US. Part of the testing battery for biocompatibility includes the in vivo Rabbit Vaginal Irritation (RVI) test. We have created an Industry Consortium comprised of personal lubricants manufacturers and are working collaboratively with...

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...

AGAR Overlay

August 22, 2016
The agar overlay assay or agar diffusion test is an in vitro cytotoxicity assay designed to show the presence of toxic material eluted from a test sample as it affects L929 cells cultured in the presence of the test article. Test articles are placed onto the agar surface overlaid onto a L929 cell monolayer preventing direct damage while allowing diffusion of leachable chemicals from the sample. After treatment, the cells are exposed to neutral red dye to differentiate between the viable...

MEM Elution

August 21, 2016
The MEM elution assay or elution test is an in vitro cytotoxicity assay designed to show the presence of toxic material eluted from a test sample as it affects L929 cells cultured in the presence of the extract. Extracts of test articles are applied to L929 cells.  After treatment, the cells are exposed to neutral red dye to differentiate between the viable and stressed or lysed cells.  The degree of irritancy is determined microscopically in the percentage of cells deformed and...

Webinar: Regulatory Initiatives for New Approaches to Traditional Toxicity Testing

July 1, 2016
This one-hour webinar features presentations by Dr. Jennifer McLain, Deputy Director, Office of Pesticide Programs, Antimicrobial Division and IIVS CEO Dr. Rodger Curren. Dr. McLain discusses the EPA OPP's plans to reduce the use of animal testing in acute toxicity testing and provides suggestions on how stakeholders and EPA can cooperate to advance animal reduction goals. Dr. Curren then talks about IIVS' activities in developing the current non-animal strategy for eye irritation, and recent investigations into in vitro methods to...
