Cell-Based Assays

Necrosis is accompanied by mitochondrial swelling and increased plasma membrane permeability, while apoptosis involves an articulated breakdown of the cell into membrane-bound apoptotic bodies. Lactate dehydrogenase (LDH) is a soluble cytosolic enzyme that is released into the culture medium following loss of...

Calcium flux assays are preferred methods in drug discovery for screening G protein coupled receptors (GPCR). This ratiometric calcium assay kit allows homogeneous measurement of intracellular calcium changes caused by activation of G-protein-coupled receptors or calcium channels. Cells expressing a GPCR of interest...

This kit makes use of an injectable green fluorescent and cell permeable probe used to quantitate caspase activity in vivo. Only cells undergoing apoptosis will fluoresce. It is an ideal reagent to asses the efficacy of chemotherapy in animals.

This kit makes use of an injectable green fluorescent and cell permeable probe used to quantitate caspase activity in vivo. Only cells undergoing apoptosis will fluoresce. It is an ideal reagent to asses the efficacy of chemotherapy in animals.

This kit makes use of an injectable red fluorescent and cell permeable probe used to quantitate caspase activity in vivo. Only cells undergoing apoptosis will fluoresce. Ideal reagent to asses the efficacy of chemotherapy.

Cayman's Lipid Droplets Fluorescence Assay Kit can be used to study regulators of lipid droplet biogenesis. The main advantage of this assay is that the green fluorescence of Nile Red is both very sensitive and specific for lipid droplets. Furthermore, changes in lipid droplet biogenesis in various cell types in...

Cayman's Phagocytosis Assay Kit (IgG FITC) employs latex beads coated with fluorescently-labeled rabbit IgG as a probe for the measurement of the phagocytic process in vitro. The engulfed fluorescent beads can be detected using a fluorescence microscope, allowing kinetic studies of phagocytosis at the single-cell...

Reactive oxygen species, such as hydrogen peroxide (H2O2) and superoxide are generated by phagocytes and participate in damaging invading miccroorganisms or other biologic targets. Cayman's H2O2 Cell-Based Assay Kit provides a simple fluorometric method for the sensitive quantitation of extracellular H2O2 produced...

Autophagy is a critical cellular process that involves the degradation and digestion of intracellular components by the lysosome. This process not only enables cells to efficiently mobilize and recycle cellular constituents, but also prevents the accumulation of damaged organelles, misfolded proteins, and invading...

Nucleosomes, which fold chromosomal DNA, contain two molecules each of the core histones H2A, H2B, H3, and H4. Almost two turns of DNA are wrapped around this octameric core, which represses transcription. The histone amino termini extend from the core, where they can be modified post-translationally by acetylation,...

Secreted alkaline phosphatase (SEAP) is commonly used as a reporter of gene expression. Compared to other conventional intracellular reporters such as chloramphenicol acetyltransferase (CAT) and firefly luciferase, SEAP has the advantage of being secreted from transfected cells into the culture medium. Cayman's...

One of the hallmarks of the early stages of apoptosis is the redistribution of membrane phospholipids such as phosphatidylserine and phosphatidylethanolamine from the inner to outer leaflet of the membrane bilayer where they are exposed on the cell surface. Externalization of phosphatidylserine residues to the outer...
