Chemical toxicology studies are routinely performed on a wide variety of compounds. The selection of specific studies to be conducted is based on the intended use of the compound and the applicable regulatory requirements. Protocols for the most commonly implemented regulatory studies are available upon request.
MB Research Labs is a leading in vitro toxicology laboratory that offers toxicological testing services to the cosmetic, chemical and pharmaceutical industries.
One of the more important assays offered in the 3T3 Neutral Red Uptake Phototoxicity (3T3 NRU PT) Assay. The 3T3NRUPT is used to screen test materials for the potential of causing photoirritation after exposure to the material and sunlight.
The 3T3 NRU PT was developed and validated in a joint EU/COLIPA project from 1992-1997. In 1996, the 3T3 NRU PT was recommended by OECD as an in vitro approach for the assessment of chemicals phototoxicity potential. In April 2004, the 3T3 NRU PT protocol was finalized and adopted as the OECD 432 protocol, In Vitro 3T3 NRU phototoxicity test.
The 3T3 NRU PT can be utilized to identify the phototoxic effect of a test substance induced by the combination of test substance and light and is based on the comparison of the cytotoxic effect of a test substance when tested after the exposure and in the absence of exposure to a non-cytotoxic dose of UVA/vis light. Cytotoxicity is expressed as a concentration-dependent reduction of the uptake of the vital dye – Neutral Red.
Substances that are phototoxic in vivo after systemic application and distribution to the skin, as well as compounds that could act as phototoxicants after topical application to the skin can be identified by the test. The reliability and relevance of the 3T3 NRU PT have been evaluated and has been shown to be predictive when compared with acute phototoxicity effects in vivo in animals and humans.
As Regulators begin to initiate laws and regulations that require the reduction of using live animals for safety studies, more and more companies are looking for valid substitutes that are economical and thorough.
Since the late 1980s, MB Research has been a pioneer in the used and development of in vitro & alternative test methods, reducing the use of live animals in toxicological research.
What are the 3 Rs?
The principle of the 3Rs was first mentioned by William Russell and Rex Burch in 1959. In their book “The Principles of Humane Experimental Technique”, they classified humane techniques under the headings Refinement, Reduction, and Replacement, commonly known now as the 3Rs.
MB Research Laboratories prides itself on pursuing in vitro and alternative toxicological methods that Reduce, Refine and Replace the use of animals in laboratory research and has worked with many leaders in this field to advance the development, validation and regulatory acceptance of in vitro and alternative tests with a goal on replacing laboratory animals in toxicological research.
Pan-American Conference for Alternative Methods (PACAM), April 12-14, 2016, hosted by Johns Hopkins University
MB Research Labs will be attending the PACAM conference. The PACAM brings together experts and stakeholders from across the Americas, with a focus on the Six Rs: Replacement, Reduction, Refinement, Read-across, Relevance, and Roadmaps.
MB Research Labs is serving on the organizing committee. MB Research Chief Scientific Officer, Dr. George DeGeorge and Director of Toxicology, Bennett Varsho, will be presenting informative talks on in vitro toxicology methods: the In Vitro Sensitization Assay (IVSA) and the Human Cell Line Activation Test (h-CLAT) as well as presenting scientific posters.
MB Research provides an extensive array of testing protocols that will help meet your regulatory requirements to ensure safe use of your products.
Rely on our experience in the classification of your fast moving consumer goods using both in vivo and in vitro testing models.
