Single-cell isolation allows genomic and transcriptomic analysis of one individual cell. It is also required to build a monoclonal cell line from rare cell isolation, that could be for example CRISPR-CAS9 gene edited cells. There are 3 popular methods: serial dilution, micro-manipulation and flow cytometry. None of these are easy or simple, and they often […]

Cardiovascular disorders: Proteomics tool for disease signature identification
Cardiovascular disease (CVD) comprehensively describes a range of pathologies of the heart and/or blood vessels. These disorders differ markedly in time-scale of development, and relative contributory effects of genes and environment. Largely due to this breadth, and their causes and effects, the range of investigation, assessment, and treatment strategies available is large. The diversity of […]
Tips and Tricks: how to increase unstable protein expression in E. Coli
Recombinant protein expression and purification for therapeutic development or for in vitro studies can sometimes be a real challenge. It requires huge investments in both time and cost in order to obtain high yields of pure and active recombinant proteins. My aim in writing this post, is to give you a simple guide to easily […]
Kupffer cells in co-culture models for liver inflammation studies
Kupffer primary cells are macrophages endogenous to the liver which have the ability to modulate hepatic inflammation and injury associated with various pathophysiologies and toxicities. Pro-inflammatory cytokines released by activated Kupffer cells, such as TNF-α and IL-6, are associated with up-regulation of acute-phase response proteins and suppression of CYP enzymes. For new biological entities, particularly […]
Cell signalling – Discover G-LISA to study Small GTPases
As is already known, multiple families of small GTPases (Ras, Arf and Rho families) make up the Ras GTPase superfamily. Due to their role as molecular switches in cell signalling (active GTP-bound state vs inactive GDP-bound states) and in many other cellular responses (cytoskeletal reorganization, regulation of transcription, apoptosis…), these small GTPases are the subject […]
Neurons, Astrocytes, Microglia: High Quality primary cells source
In the field of neurosciences, increasing research is being undertaken on neurodegenerative disorders like Parkinson’s and Alzheimer’s diseases, as well as on nerve injury and regeneration. One of the challenges researchers face is finding the appropriate cellular neuromodels, as close as possible to the in vivo environment. Primary cells are one of the answers, increasingly […]
Cancer immunotherapy: explore the cytokine “milieu” with Quantibody 200 Biomarker Service
Autologous tumour cell vaccines vs. dendritic cell vaccines: What’s best, and why? Understanding the best approach for tumour vaccinations is of growing importance in the personalized cancer immunotherapy field. Current models use a variety of treatments, but two include the use of irradiated autologous tumour cells (TCV), or autologous dendritic cells loaded with tumour associated […]
HDACs: Active drug targets for Immunotherapy treatment
For many pathologies such as cancer or neurological disorders, it has been found that Histone Deacetylase (HDAC) activity is disrupted, making them promising targets for drug development. Scientists need access to a broade range of products ( Active Enzyme, inhibitors/activators, Biochemical screening assays…), to simplify their research and identification of HDAC inhibitors.
Antibody reproducibility: what will make the difference…
Rockland Immunochemicals, Inc., (Rockland) provide the highest quality antibodies to the academic, biopharma, and diagnostic industries for use in basic research, assay development, preclinical and clinical studies, and bioprocessing. With facilities in Pennsylvania established since 55 years ago, Rockland manufactures products ideally suited for integration into critical assays such as western blotting, immunohistochemistry (IHC), immunofluorescence […]
Maximize metabolic activities by limiting Hepatocyte cryoinjury
I am following up on my series of posts based on the work done by Chris Bohl and collaborators at Sekisui Xenotech. Here, he looks at the effect of cryopreservation on pooled hepatocytes metabolic activities, and how the patented Cryostax technology can address this issue.
Live Cell Imaging – Watch Human Osteosarcoma cells in action, stained with SiR-Tubulin probes
As you may already know, Spirochrome have developed a broad range of Live Cell Imaging probes for the staining of DNA, Lysosome, F-Actin and Microtubules.
