Abnova offer a series of new monoclonal research antibodies to support the study of the Zika virus. These are available through tebu-bio across Europe. Let’s take a look at these monoclonals, 100% validated for immuno-assay applications.
Protein Gene Product 9.5 (PGP 9.5) is an abundant cytoplasmic neuron and neuroendocrine-cell specific protein. Over the years, this deubiquitinating enzyme (a.k.a. Ubiquitin Carboxy-terminal Hydrolase L1 (UCH-L1)) has become an accepted biomarker for neurons and cells of the diffuse neuroendocrine system (DNES) but also when studying neurodegenerative disorders (e.g. Alzheimer’s and Parkinson’s diseases) and cancers.
Research antibodies specific for PGP9.5 / UCH-L1 stain neuronal cell bodies and axons in the central and peripheral nervous systems, small nerve fibres in nerve tissue, neuroendocrine cells in the pituitary, thyroid pancreas, and also tumours of the DNES.
In this context, Cedarlane just release 2 new anti-PGP9.5 / UCHL1 rabbit polyclonal antibodies fully validated & guaranteed for IHC analysis of Paraffin Embedded Sections, IF and WB applications on Human, Rat and Mouse tissues. [Read more…]
Mitochondria keep cells “healthy” in their environment. In this post, we’ll take a look at a new fluorescent assay for the monitoring of mitophagy, a process aimed at clearing damaged or superfluous mitochondria by autophagy, in mammalian cells.
Multicolour fluorochrome reagents have spurred researchers’ capacity to analyze cell populations and to isolate cell subsets by flow cytometry. In this post, let’s take at look at the advantages of 5 optimized combinations of mixed fluorochromes you should consider for your next immunophenotyping assays by multicolour flow cytometry.
Reactive Oxygen Species (ROS) are reactive molecules and free radicals derived from molecular oxygen involved in cellular homeostasis. An excess of ROS production (e.g. exposure to environmental stress such as UV or heat exposure) causes significant damage to cell structures. In this post, let’s review the research tools for studying this process also known as Oxidative stress.
Autophagy was first described in the 60s, and it presents clear differences vs apoptosis. While apoptosis is a mechanism that kills the cells (apoptosis = self-killing), autophagy is more related to the orderly degradation and recycling of cellular components (autophagy = self-eating). [Read more…]
Renal injury can sometimes be induced by drugs. Some examples of renal damage-inducing drugs include some widespread treatments, such as ß-Lactam antibiotics, bisphosphonates, non-steroidal anti-inflammatory drugs, diuretics, aminoglycoside antibiotics, antineoplastic agents and radiocontrast agents.
Since 2008, both the FDA and the EMEA indicated that additional tests may be necessary to assess new drug safety and prevent from renal toxicity. Though these recommendations are voluntary, many pharmaceutical companies have started gathering data on nephrotoxicity biomarkers. [Read more…]
Small molecules known to modulate biological activies of the K-Ras oncogene are predominantly of synthetic origin (ex. Salirasib). Nevetheless, various publications have recently demontrated the biological potential of microbial metabolites in KRAS studies. Here’s a good opportunity to briefly review a few of these compounds.
Singlet Oxygen (1O2) fluorescent detection in living cells was limited by the lack of availability of cell membrane permeable dyes. The silicon-based far-red fluorescent probe (Si-DMA) has been especially designed to monitor singlet oxygen in real-time and in living cells. Si-DMA is now commercially available for ROS studies by live-cell imaging.
