The DPRA is an in chemico method which quantifies the remaining concentration of cysteine- or lysine-containing peptide following 24 hours incubation with the test chemical at 25 +/-2,5ºC. The synthetic peptides contain phenylalanine to aid in the detection. Relative peptide concentration is

The neutral red uptake (NRU) assay provides a quantitative measurement of the number of viable cells. The test is based on the ability of living cells to take up and bind neutral red (NR), a dye which easily penetrates cell membranes via non-ionic diffusion and accumulates in the lysosomes. Dying

The in vitro Alkaline Comet Assay is a microgel electrophoresis technique which allows to measure DNA damage (single and double strand breaks, alkali labile sites, incomplete excision repair sites and cross links) cell by cell. Cells are mixed with 0.8% Low Melting Point Agarose which is spread as a

The Ames test is a short-term bacterial reverse gene mutation assay specifically designed to detect a wide range of chemical substances that can produce genetic damage that leads to permanent gene mutations. The test has been described in detail in OECD TG 471 and employs several histidine dependent

By using in vitro co-cultures of immune cells and lung tumor cells, we can study and evaluate the immune-activating and/or anti anti-tumor properties of certain treatments. Tumor cell proliferation can be studied with live-cell imaging instruments (IncuCyte, EVOS, ...) and the occurrence of immune

Alkaline comet assay (COM) and Micronucleus test (MN) are well-established cytogenetic tests that are used to detect both immediate damages i.e. DNA fragmentation, and permanent damage which results in micronuclei formation. These techniques are often applied separately or, sometimes, in combination

Spheroids are three-dimensional cellular models with widespread basic and translational application across academia and industry. However, methodological transparency and guidelines for spheroid research have not yet been established. The MISpheroID Consortium developed a crowdsourcing knowledgebase

Fever-inducing substances need to be traced in medical packaging material. To do so, in the past, rabbits were often exposed to these substances. Causing enormous amounts of animal suffering. Nowadays this test has been largely replaced by the so-called LAL (Limulus amebocyte lysate) test, which
