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 main objective of this research project is to create the first full-thickness cornea-on-chip, which comprises a 3D construct with every cellular layer of the cornea. This construct is embedded in a microfluidic chip with two channels that are continuously perfused. The epithelial side of the

A battery of in vitro genotoxicity assays is currently used to detect agents with DNA damaging and carcinogenic potential. Although the sensitivity of this battery of genotoxicity assays is high, the specificity is low (“false positive hit”), especially with the mammalian cell-based assay, compared

The purpose of the present development is to use avian MoDCs to implement a cellular platform to increase understanding of the immune responses induced by various antigens of interest (e.g. vaccine candidates) and evaluate their immunogenic potential. Considering the difficulty to work on dendritic

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

The CALUX method is an in vitro bioassay that uses reporter gene cell lines that have been stably transfected with a luciferase reporter gene under the control of relevant receptor specific DNA response element. This enables the screening for chemicals that can bind to specific receptors and

The neutral red uptake assay is a cell viability assay that allows in vitro quantification of xenobiotic-induced cytotoxicity. The assay relies on the ability of living cells to incorporate and bind neutral red, a weak cationic dye, in lysosomes. As such, cytotoxicity is expressed as a concentration

The monocyte-activation test (MAT) is used to detect or quantify substances that activate human monocytes or monocytic cells to release endogenous mediators such as pro-inflammatory cytokines, for example tumour necrosis factor alpha (TNFα), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6). These

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
