Cultivated liver cells are fixed with 4% (w/v) paraformaldehyde (PFA) for 10 minutes at room temperature and subsequently incubated for 15 minutes with 100 mM glycin solution, used to saturate reactive groups generated after PFA fixation. These cells are subsequently incubated for 10 minutes with 1%

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that

E. coli is one of the organisms of choice for the production of recombinant proteins. DH5 alpha cells are commonly used for maintenance, propagation and mutation, whilst BL21(DE3) and C43(DE3) are mainly used for expression of the transgene. The advantage of C43(DE3) is that is used to produce

The VITOTOX test is a bacterial genotoxicity test. The test is based on bacteria that contain the lux operon of Vibrio fischeri under transcriptional control of the mutated recN promoter, which is controlled by the bacterial SOS-system (TA 104-recN2-4 strain or Genox strain). After incubation

This method uses human skin-derived precursors (hSKP) differentiated towards hepatic cells (hSKP-HPC) as a hepatic in vitro model. Exposure of these cells for 24 hours to sub-cytotoxic concentrations of acetaminophen, which is a reference hepatotoxicant, induced specific cellular responses in a

The CALUX® system (Chemically Actived LUciferase eXpression) of Bio Detection Systems (BDS, Amsterdam, the Netherlands) uses U-2 OS cells (human osteoblast) that are stably transfected with human TRb or human PPARg2 (BDS, Amsterdam) and a luciferase reporter construct under the control of a receptor

The ATP cell viability assay (CellTiter-Glo assay test kit) provides a quantitative measurement of the ATP content directly proportional to the number of cells present in culture. The homogeneous assay procedure involves adding one single reagent, CellTiter-Glo Reagent directly to cells cultured in

The tetanus neurotoxin (TeNT) is one of the most toxic proteins known to man, which prior to the use of the vaccine against the TeNT producing bacteria Clostridium tetani, resulted in a 20% mortality rate upon infection. The clinical detrimental effects of tetanus have decreased immensely since the

Lung cancer thrives in a complex multicellular tumor microenvironment (TME) that impacts tumor growth, metastasis, response, and resistance to therapy. While orthotopic murine lung cancer models can partly recapitulate this complexity, they do not resonate with high-throughput immunotherapeutic drug

This model is a 3D human co-culture model where both hepatocyte functionality and HSC quiescence can be maintained for at least 21 days. This novel system allows hepatotoxicity testing and can detect drug-induced as well as hepatocyte-dependent HSC activation, thereby representing an important step
