Protein arrays enable the analysis of the biological function / activity of dozens to hundreds of proteins in one experiment (e.g. auto-antibody detection, protein-protein interactions, small molecule screening…). In this post, let’s review the recent Raybiotech Protein Arrays focusing on Immunology.
Research tools aimed at exploring mitochondria are becoming more and more popular and cover multiple experimental applications. They go from primary antibodies validated for immuno-assays (see “10 Mitochondrial marker antibodies“) to fluorescent probes for mitochondria-related events monitor in living-cells (e.g. MitoPeDPP for live cell imaging, mitophagy or singlet Oxygen (1O2) detection…). Here I’d like to introduce 3 new molecules developed by Focus Biomolecules to further decipher mitochondrial biology.
The human Flap Endonuclease 1 (a.k.a. hFEN1) is a structure-specific nuclease involved in DNA replication and repair. This nuclease is thought to be a potential therapeutic target for treating cancers (e.g. chemosensitization, synthetic lethality) hence, the need for discovering and characterizing new hFEN1 inhibitors.
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…]
