EpiDermTM in vitro skin irritation assay
In vitro data were obtained using the EpiDerm
Skin Irritation Test Protocol (Kandarova et al., 2005),
as evaluated in ECVAM Skin Irritation Validation
study (Spielmann et al., 2007). In this assay, the
prediction model is based on determining the
viability of 3 tissues exposed to a chemical (15 min
min initial exposure followed by rinse off and a 42h
post-incubation) referenced to unexposed, negative
control tissues. The modified protocol employed
prolonged exposure (60 min). If the tissue viability
(as determined using the MTT assay) of chemicalexposed
tissues is reduced to 50% or less, the
chemical is classified (in both protocols) as an irritant;
if the tissue viability exceeds 50%, the material is
classified as a non-irritant.
