Comprehensive Solutions for Autophagy

Autophagic activity is critical to the maintenance of cellular homeostasis and energy balance. Although typically low under basal conditions, autophagy can be markedly upregulated by a variety of physiological stimuli such as nutrient starvation, hypoxia, endoplasmic reticulum stress, as well as immune and hormonal stimulation. With our innovative assays and reagents, Enzo enables scientists to gain a deeper understanding of the benefits, and potential consequences, of altering autophagic activity.

Comprehensive Solutions for Cytotoxicity

Cytotoxicity, or the quality of being toxic to cells, is a cellular regulator which can result in a variety of cell fates. Most often, it results in a variety of types of cell death – including necrosis, where the cell dies as a result of cell lysis; apoptosis, a form of programmed cell death; or other fates. Enzo provides a variety of assays to quantify cytotoxicity in cells, including an LDH Cytotoxicity WST Assay and Cell Counting Kit 8.

Flow Cytometry

Flow cytometry allows researchers to measure several physical characteristics of cells including its shape, size, and internal complexity. It has long been used in cell counting and cell sorting but more recently, researchers have been using flow cytometry in a broad range of applications including: biomarker detection, cell signaling, pathway screening, protein engineering, and systems biology. Flow cytometry is inherently a robust technique that adapts easily to basic research, drug development, and diagnostics.

Enzo Life Sciences offers a variety of flow cytometry-based assays for cell viability, proliferation and death analysis, available in a wide range of formats to meet individual research needs. We also offer unique flow cytometry-based assays to measure oxidative stress and to profile multi-drug resistance. These flexible assays are compatible with all flow cytometry platforms, regardless of size or functionality. The assays are easy to perform and can be run quickly using small sample input, without sacrificing sensitivity.

In addition, Enzo Life Sciences offers more than 600 antibodies that have been validated for flow cytometry. These include isotype controls as well as biotin and fluorescent conjugates for use in evaluating intracellular and extracellular proteins.

Oxidative Stress

The term oxidative stress reflects an imbalance in free radical formation within a cell or organism, most commonly in the form of reactive oxygen or nitrogen species (ROS/RNS). ROS/RNS such as superoxide anions, hydroxyl radicals, hydrogen peroxide, nitric oxide, and peroxynitrite originate from a variety of sources including changes in aerobic metabolism, immune activation, UV radiation, heme accumulation, and hypoxia. Failure of the cell’s defense mechanisms to compensate for accumulating insults such as mitochondrial dysfunction, DNA damage, misfolded proteins, and lipid peroxidation can trigger programmed cell death pathways, and has been linked to clinically relevant diseases including cancer, cardiovascular disease, asthma, ischemia, diabetes, and neurodegenerative disease.
