  • Vitamin D ELISA Kit

    Cayman Chemical

    The primary synthesis of functional vitamin D begins in the skin, where a cholesterol by-product acted upon by UV light forms vitamin D3. Vitamin D3 is carried through the bloodstream, attached to the vitamin D binding protein, to the liver where it is converted to 25-hydroxy vitamin D3 (25(OH)D3).…

  • 11-KT is a second key androgenic steroid found in fish. It occurs in males together with testosterone in amounts which vary from less than 1 ng/ml to as much as 50-100 ng/ml, depending on the species and the stage of the reproductive cycle.

  • Urea Fluorometric Assay Kit

    Cayman Chemical

    Urea is the final degradation product of protein and amino acid metabolism. Urea is found in blood and is excreted by the kidney as a component of urine. Besides its role as carrier of waste nitrogen, urea also plays a role in the countercurrent exchange system of the nephrons, allowing for…

  • Corticosterone ELISA Kit

    Cayman Chemical

    Corticosterone is a glucocorticoid produced by the adrenal cortex in response to ACTH (adrenocorticotropic hormone), and is the precursor to aldosterone. The production of glucorcorticoids is increased by stress; therefore, corticosterone can be used as a biomarker of stress. Plasma corticosterone…

  • Cayman Practice ELISA Kit

    Cayman Chemical

    This assay has been developed for researchers that do not have experience performing ELISAs. It can be used as a practice tool allowing you to become comfortable with running Cayman ELISAs. This kit contains enough reagents to run at least four complete standard curves.

  • Testosterone ELISA Kit

    Cayman Chemical

    Testosterone is the prototypic and predominant circulating androgenic steroid. It plays a major role in the growth and function of many reproductive and non-reproductive tissues and organs including muscle, liver, and brain, directing the development of the male phenotype during embryogenesis and…

  • Cortisol Express ELISA Kit

    Cayman Chemical

    Cayman's Cortisol Express ELISA is a competitive assay that permits the rapid measurement of cortisol from biological samples, requiring only a two hour incubation and one hour development times.

  • Aldosterone ELISA Kit

    Cayman Chemical

    Aldosterone, a steroid hormone secreted by the adrenal cortex, is the principle mineralocorticoid controlling sodium and potassium balance. Serum aldosterone levels in normal upright adult individuals are generally less than 300 pg/ml. Only a fraction of urinary aldosterone is excreted intact, thus…

  • Cortisol ELISA Kit

    Cayman Chemical

    Cayman’s Cortisol ELISA is a competitive assay that provides accurate measurements of cortisol within the range of 6.6-4,000 pg/ml.

  • Cayman's 8-Hydroxyguanosine (8-OHG) ELISA Kit is a competitive assay that can be used to measure both 8-hydroxy-2'-deoxyguanosine and 8-hydroxyguanosine. This kit has been validated for use in urine, but other sample types may be used. The assay has a range from 0.15-20 ng/ml and a…

  • Complex I (NADH oxidase/Co-enzyme Q reductase) is one of the major sites of electron entry into the mitochondrial electron transport chain (ETC). Complex I catalyzes the 2 electron oxidation of NADH followed by the reduction of ubiquinone (Q) to form ubiquinol (QH2), and ultimately the reduction of…

  • Cayman’s Cell Cycle Phase Determination provides an easy to use tool for studying the induction and inhibition of cell cycle progression in any cell suspension sample. The assay involves the fixation and permeabilization of the cells of interest, making possible the staining of DNA within…

  • Lipase Activity Assay Kit

    Cayman Chemical

    Lipases perform essential roles in the digestion, transportation, and processing of dietary lipids by controlling the clearance of triglyceride-rich lipoproteins from the circulation. Manipulating lipolysis has therapeutic potential in the metabolic disorders frequently associated with obesity.…

  • Both DNA and RNA are damaged by oxidation during aging and in a variety of disease states including cancer. The repair processes that are initiated to correct this damage release multiple oxidized guanine species into the urine. Cayman Chemical has developed this immunoassay for the measurement of…

  • Cayman’s PC Assay provides a specific, sensitive, and convenient method for quantifying PC in plasma or serum. In this assay, PC-Specific PLD hydrolyzes PC to choline and phosphatidic acid. The newly formed choline is then used to generate hydrogen peroxide in a reaction catalyzed by choline…

  • 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. Cancer cells exhibit increased glucose uptake and metabolism by…

  • MAGL is the main enzyme responsible for the inactivation of 2-AG. Cayman’s Monoacylglycerol Lipase Inhibitor Screening Assay provides a convenient method for screening human MAGL inhibitors. MAGL hydrolyzes 4-nitrophenylacetate resulting in a yellow product, 4-nitrophenol, with an absorbance…

  • Complex II (succinate dehydrogenase/co-enzyme Q reductase) is one of the major sites of electron entry into the mitochondrial electron transport chain (ETC). Complex II catalyzes the oxidation of succinate to fumarate, and in the process reduces ubiquinone (Q) to ubiquinol (QH2). Ultimately,…

  • DNA Methylation ELISA Kit

    Cayman Chemical

    DNA methylation is an important epigenetic process regulating gene expression. Methylation occurs on carbon 5 of 2-deoxy cytidine yielding the modified base 5-methyl-2-deoxy cytidine. The methylation pattern of cells is tightly regulated during development with the methylation profile being…

  • GSTs are ubiquitous multifunctional enzymes, which play a key role in cellular detoxification. The enzymes protect cells against toxicants by conjugating them to glutathione thereby neutralizing their electrophilic sites and rendering the products more water-soluble. Cayman’s GST Assay…

  • Purified MIS for ELISAs.

  • Enterolactone ELISA Kit

    Cayman Chemical

    Enterolactone is a mammalian lignan with an estrogen-like diphenolic structure. It is produced by intestinal bacteria from two plant precursors (matairesinol and secoisolariciresinol) obtained in the diet. Enterolactone and other lignans and phytoestrogens have been associated with a reduced risk…

  • Estriol ELISA Kit

    Cayman Chemical

    Estriol, a metabolite of 17b-estradiol and a major estrogen produced during pregnancy. In the final weeks before parturition, estriol levels increase significantly (10 weeks gestation to approximately 150 ng/ml at week 38). The majority of the estriol synthesized in the later stages of pregnancy…

  • Maintaining body cholesterol homeostasis is critical for normal physiological functions and is achieved by a highly regulated balance of de novo synthesis, dietary cholesterol absorption, biliary clearance, and excretion. The mechanisms controlling cholesterol absorption are important to understand…

  • 2-Methoxyestradiol (2-ME2) is a natural metabolite of estradiol with potent antitumor and antiangiogenic properties. 2-Methoxyestradiol is a natural metabolite of estradiol with potent antitumor and antiangiogenic properties. Cayman’s 2-Methoxyestradiol ELISA is a competitive assay that can…

  • Progesterone ELISA Kit

    Cayman Chemical
