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

We have developed a protocol for culturing primary neuron progenitor cells (NPCs) derived from mouse embryos at embryonic day 15 (E15). These cells are highly proliferative, can be subcultured and cryopreserved and can be differentiated to neurons or astrocytes. Hence, this method can greatly reduce

The in vitro rumen fermentation technique is used to simulate the rumen function/fermentation. The rumen is the first compartment of the digestive tract of ruminants, in which feed - consumed by ruminants - is fermented by rumen microbes. For optimal fermentation, the rumen provides an anaerobic

The tri-dimensional (3D) culture protocols allow isolation and culture of gastric epithelial antral and intestinal stem cells to efficiently generate organoids that recapitulate the mature pyloric and intestinal epithelium in vitro and foetal epithelial progenitors of these tissues growing as

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

DARTpaths is an an integrative app to support the prioritisation of chemicals. The Open Source R shiny application allows for the prediction of compound-induced molecular mechanisms of action. The tool integrates phenotypic endpoints of different species induced by compounds and genetic variants, in

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
