Decidedly, producing and purifying a protein is a form of art. Indeed, each recombinant protein (rec. protein) to be produced in vitro has specific characteristics and singularities that make its production and purification most definitely challenging. In this post, I’d like to share and review a few tips and basics for optimal design of experiment […]

3D cell culture Biochip – versatile for more physiological applications
By mimicking in-vivo environments, 3D cell culture models appear nowadays as the best in-vitro study model to work in an in-vivo like study model and to obtain more physiologically relevant data and proof of concept as close as possible to “a clinical context”. To accompany researchers along this way, there are several innovative cell culture […]
ELISA tests, arrays and cellular models for Obesity and Diabetes
If your research is related to obesity and adipose tissue, you may be interested by the selection I have performed below of immunoassays (including ELISA tests and antibody arrays), as well as primary cell models related to this topic. Obesity and the diseases arising from it (diabetes, cardiovascular disease and cancer) constitute a major health […]
ADME-Tox: liver fractions with High Aldehyde Oxidase and Xanthine Oxidase Activity
Sekisui XenoTech has just established a method for high Aldehyde Oxidase and Xanthine Oxidase activity in pooled Human liver test systems. These new test systems (Pooled Human Liver S9 and cytosol) have been prepared from tissue treated to preserve high Aldehyde Oxidase (AO) and Xanthine Oxidase (XO) activity, yet without significantly impacting major cytochrome P450 […]
Pluripotent stem cells for improved reprogrammed Human Sebocytes
Following the start of our recent collaboration with Phenocell, we’re pleased to be able to provide high quality Sebocytes developed from Human induced pluripotent stem cells (iPSC). Thanks to a perfectly standardized reprogramming protocol, they display lower batch to batch variability, allowing better reproducibility and accuracy of your experimental results.
Cell-based assays with hPBMCs for cell therapy and drug discovery
Human Peripheral Blood Mononuclear Cells (hPBMCs) are essential for designing cellular models to be used in cell therapy and drug discovery research programs [1-7, 12]. Being able to access reliable and ethical sources of well-characterized hPBMCs is now becoming fundamental for running physiologically relevant cell-based assays. A good opportunity to discuss the expanding applications for […]
cAMP signals visualized in live human pancreatic primary cells
In a recent publication, researchers from the University of Miami Miller School of Medicine (USA) describe that Serotonin released by human beta cell inhibits glucagon secretion by alpha cells. They demonstrated that this paracrine loop was mediated via the cAMP pathway. To do so, they captured in live human pancreatic islet cells cAMP signals using […]
Microcell arrays – obtain more accurate data from single living cells
Understanding how mammalian cells function requires a dynamic perspective. Recent improvements in our abilities to perform fluorescence microscopy on primary cells, coupled with advances in pipelines for quantifying and extracting data, have made possible a better understanding of the temporal complexity of cell signalling pathway. Due to the heterogeneity seen in both eukaryotic and prokaryotic cell […]
Analysis tool for direct and sandwich ELISA – convenient and reliable
Many ELISA kits – one analysis tool Analyte quantification (in pg/ml or ng/ml) such as IL-6, TNFalpha and numerous other proteins is conveniently performed with immunoassays called ELISA kits. At tebu-bio, we not only provide more than 10 000 ELISA kits but we also support researchers through our techserv team who are on-hand to suggest […]
Cell Signalling: Ras-Raf-MEK-ERK pathway research tools
The Ras-Raf-MEK-ERK Pathway is an important cell signalling route with many implications for cancer biology and therapeutic development. Dis-regulation of some of this pathway’s proteins expression and phosphorylation status are observed in about one-third of all human cancers. Access to specific tools to study this pathway is essential to a better understanding of its role […]
Optimizing the CAS9 messenger RNA for vector-free gene editing
Sequence engineering and chemical modification of CAS9 mRNA For transgenesis and therapeutic perspectives, vector-free delivery of the CAS9 for gene editing is highly preferable. It avoids the risk of hitting the genome due to the vector integration. Directly using CAS9 mRNA is a top option. Furthermore, as a new promising class of therapeutic biologics, messenger […]
