New study at LAUS


We now offer Spray Pattern Testing for Biocides and Pesticides acc. FEA 644 (European Aerosol Federation) under GLP.
This method is helpful for the rapid characterisation of aerosol sprays and will provide a guide to the size and distribution of droplets within a spray pattern.
It is a required parameter during storage stability testing for spray applications.

All three in vitro skin sensitisation studies available under GLP

LAUS NEWS: All three in vitro skin sensitisation studies available under GLP

LAUS has established and fully validated the h-CLAT (human Cell Line Activation Test, OECD 442E) and is now able to perform all three studies available for in vitro skin sensitisation testing under GLP conditions (h-CLAT, DPRA, LuSens).

The h-CLAT (human Cell Line Activation Test) uses the human monocytic leukemia cell line THP-1. The up-regulation of the surface molecules CD54 and CD86 as markers of dendritic cell activation is measured by flow cytometry following cell staining with fluorochrome-tagged antibodies.

In vitro skin sensitisation testing can substitute the corresponding in vivo study, the LLNA (OECD 442B and 429), in many cases. Unlike the LLNA, which is a stand-alone study, in vitro skin sensitisation testing consists of an array of three studies, each of them targeting a key event in the Adverse Outcome Pathway (AOP) of skin sensitisation. A substance can be rated as a sensitiser with two consistent positive results.


Key event of AOP





covalent interaction with skin proteins




keratinocyte response

dendritic cell activation



The tests are interesting for clients from the following regulatory areas:

  • REACH (EC 1907/2006)
  • The CLP Regulation (EC 1272/2008)
  • The Biocidal Products Regulation (EC 528/2012)
  • The Plant Protection Products Regulation (EC 1107/2009)
  • The Cosmetics Regulation (EC 1223/2009)
  • And screening at non-regulatory stages of product development
