Glutathione (GSH) is a tri-peptide (Glutamic acid, Cystein and Glycine) present in cells, showing an antioxidant effect allowing the reduction and the removal of Reactive Oxygen Species (ROS) and Peroxide from the cell. The new QuicGSHS3.0 probe from Goryo Chemicals will allow you to easily quantify intracellular concentration of GSH by Fluorescent Live cell Imaging.
Due to its involvement in many cellular processes such as normal ageing, tumor suppression, chronic diseases and many more, cellular senescence has gained increasing attention since its first description over 50 years ago. In addition, understanding of cellular senescence is invaluable in the development of therapeutic targets in the fight against age-related co-morbidities, cancer and chronic disease progression.
Over-expressed in senescent cells, Senescence-associated β-galactosidase (SA-β-gal), has been widely used as a marker of cellular senescence. In order to specifically detect this biomarker directly in living cells or tissues, let’s take a look at an easy and ready-to-use assay recently developed: the SPiDER-βGal- Cellular Senescence Detection kit.

Live Cell Imaging has transformed the way biologists study cellular functions and processes. The observation of dynamic changes provides more insight into the processes happening in a cell, as compared to imaging studies of fixed cells. Goryo Chemical have developed a broad range of innovative Live Cell Imaging fluorescent probes for various applications. Let’s take a closer look… [Read more…]
One of our aims is to offer you, the researcher, a large and varied selection of biologically relevant, innovative Live Cell Imaging tools. In 2016, we started a collaboration with Goryo Chemical, when our specialists selected their unique fluorescent dyes for cellular analysis, assays and live cell imaging.
In one of my previous posts, I already invited you to take a (non-exhaustive) look at their diversified range of fluorescent dyes, which can be used in a variety of fields such as stem cell differentiation, cancer cell studies, Reactive Oxygen Species (ROS) analysis… Today, I’d like to take you through two new fluorescent probes we’re pleased to make available for you.
Reactive oxygen species (ROS) play key roles in various intracellular processes and have been shown to be involved in many diseases (eg. carcinogenesis, inflammation…). Each of the ROS species is likely to have a specific role in living cells. Therefore, there is an emerging need for selectively detecting each species of ROS through conventional biochemical assays, but also in live cell imaging (see a previous post “Reactive Oxygen Species (ROS) and related assay kits“).
The detection of molecular events in living cells is booming. In this post, we look at 3 fluorescent probes that will undoubtedly count in the live-cell imaging landscape in 2017.
Focus Biomolecules produces a broad range of bioactive lipid mediators as well as many small molecule inhibitors of numerous lipid metabolic pathways for use as cellular probes. These can be supplied as individual products or in a library format (Focus Biomolecules products are available through tebu-bio in Europe). Pathways include Anandamide, Lipo-amino acid, Prostaglandin, Leukotriene, Sphingolipid, Fatty Acid, Cholesterol and more. [Read more…]
The ubiquitin-proteasome system (UPS) is a well-characterized protein degradation system in cells whose dysfunction is implicated in many diseases, including neurodegeneration and cancer1,2. Major UPS components are ubiquitin (Ub), Ub ligases, Ub hydrolases (deubiquitinases [DUBs]), and the proteasome.
In the field of Drug Development, 3D cell culture models such as spheroids or organoids currently appear as one of the best solutions to obtain accurate and physiological in vitro data, closest to what occurs in the human body. These models are the perfect intermediary between “less realistic” classical in vitro static screening well plates, and animal models which, although more relevant, are much more complicated to set up, and are time consuming.
