Adaptation of the human Cell Line Activation Test (h-CLAT) to Animal-Product-Free Conditions.

Skin sensitisers are substances that can elicit allergic responses following skin contact and the process by which this occurs is described as skin sensitisation. Skin sensitisation is defined as a series of key events, that form an adverse outcome pathway (AOP). Key event three in the AOP is dendritic cell activation that can be modelled by the human Cell Line Activation Test (h-CLAT) and is typified by changes in cell surface markers CD54 and CD86 in dendritic cells.

Adaptation of the KeratinoSens™ skin sensitization test to animal-product-free cell culture.

Skin sensitization is the process by which a substance induces an allergic reaction following skin contact. The process has been described as an adverse outcome pathway (AOP), including several key events, from skin penetration and covalent protein binding, to keratinocyte activation, dendritic cell activation and T-lymphocyte proliferation. The in vitro assay KeratinoSens™ measures the activation of keratinocytes.
