Cell-Based Assays

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 level. In addition, the flow cytometric readout provides the...

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 microorganisms. Autophagy is a multi-step process that begins...

Glucose metabolism is a primary source of energy and biomaterials for the maintenance of cell homeostasis. Extra glucose is stored in the muscles and liver as glycogen which is hydrolyzed to glucose and released into the blood when needed. The rate of glucose uptake in cells is dynamic and tightly regulated by hormones and/or growth factors including insulin. Cancer cells...

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 that signals through calcium are pre-loaded with Fura-2 AM...

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 response to different manipulations can be both qualified and...

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 by cultured cells. H2O2 is detected using ADHP...

Mammalian soluble epoxide hydrolase (sEH) is a member of the alpha/beta-hydrolase fold family of enzymes that catalyze the hydrolysis of exogenous and endogenous epoxides to vicinal diols. sEH is a homodimer consisting of two domains. The C-terminal domain is responsible for the epoxide hydrolase activity while the N-terminal domain has a catalytic center with phosphatase...

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, phosphorylation, ubiquitination, and methylation, affecting...

The Melanocortin-3 receptor (MC3R) helps regulate energy homeostasis and mice lacking MC3R have increased fat mass and reduced lean mass. Therefore, agonists that selectively activate MC3R might have beneficial effects related to weight gain and glucose metabolism. This assay consists of a 96-well plate coated with a transfection complex containing DNA constructs for MC3R...

The melanocortin-4 receptor (MC4R) has important roles in weight regulation, sexual function, and inflammation. Mice deficient in MC4R have increased lipid deposition associated with elevated adiposity, while mutations in MC4R in humans are associated with early onset or severe obesity. This assay consists of a 96-well plate coated with a transfection complex containing DNA...

Surface Transfection and Expression Protocol (STEP(TM)) is a novel, patented, solid phase transient transfection technology that overcomes many of the disadvantages of other transfection approaches. CaymansOrexin 1 Receptor (OX1R) STEP(TM) Reporter Assay Kit (Luminescence) consists of a 96-well plate coated with both OX1R and Secretory Alkaline Phosphatase (SEAP) reporter...
