Sensitivity testing (DPRA and MUSST)

The DPRA (Direct Peptide Reactivity Assay) test assesses the potential allergenicity of an ingredient by its reactivity with peptides. The MUSST (Myeloid U937 Skin Sensitization Test) measures the expression of sensitization biomarkers on U937 cells. Together, these in vitro tests replace animal tests for predicting skin sensitization.

At YesWeLab, we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods.
If you have any particular requirements, please do not hesitate to specify them in your request: our scientific team will do everything possible to respond accurately and promptly.
Since 2020, numerous manufacturers, distributors, and engineering firms have entrusted us with the management of their analyses, sending us their samples through our digital platform.
