Introduction
The Genomic Allergen Rapid Detection (GARD) assay is a state of the art in vitro assay developed for the assessment of skin sensitizers. It is based on gene expression analysis of SenzaCells, a human myeloid cell line, after stimulation by the test item.
During the development of the GARD platform, two solvents were used; DMSO (0.1%) and Water. To increase the applicability domain of GARD® and the solubility of certain test items, for e.g. Medical Device extracts and UVCBs, we here show a broader range of solvents compatible with GARD.
Conclusions
Here, we show that the GARD® platform is compatible with the following solvents:
• Acetone
• Ethanol
• Glycerol
• Super refined olive oil
• DMF
• DMSO
• Water
• Isopropanol
