Researching Cortisol? Use the 'gold standard' assay

  Why do researchers consider Salimetrics salivary assays the standard of comparison? Because they are competitively priced, provide accurate, repeatable results, and are used by thousands of researchers in more than 20 countries worldwide. Salimetrics offers the most reliable, repeatable and most accurate results in saliva, because it is focused on science driven by rigorous, uncompromising testing.    Salimetrics supports thousands of saliva researchers in many countries around the world and its customer support staff is unparalleled.   The Salimetrics Salivary Cortisol ELISA Kit was specifically designed to standardize the quantitative determination of free cortisol concentrations in saliva samples for research and biomedical laboratories. Using a small sample volume, this assay kit has an extended range that spans the expected cortisol levels found in human saliva. The average inter- and intra-assay precision coefficients of variation are low with no deleterious matrix effects often found in saliva which are characterized through dilution- and spike-recovery validation procedures.   The Salimetrics cortisol assay kit has also been formatted to minimize cross reactivity for related steroids. Salimetrics salivary assay kits are expertly designed, developed and validated to ensure accuracy in saliva and proven to deliver precision results for biomarkers in saliva .Salivary cortisol levels are unaffected by salivary flow rate and are relatively resistant to degradation from enzymes or freeze-thaw cycles. Studies consistently report high correlations between serum and salivary cortisol, indicating that salivary cortisol levels reliably estimate serum cortisol levels. Cortisol production has a circadian rhythm, with levels peaking in the early morning and dropping to lowest values at night. However, levels rise independently of circadian rhythm in response to stress.​   Here is the specification:   Target Analyte: Cortisol Format:96-well plate Type: Quantitative Method: ELISA/EIA Calibrator range: 0.012-3.000 ug/dL Sensitivity:  Saliva volume/test: 25 µL Incubation time: 1.5 hours Tests per kit:  76 (singlet) Correlation with serum: 0.91 Controls included in kit? Yes Download Specification   Here is the Price:   Cortisol Research Assay (76 singlet tests):£179 per Kit (€250.60) Cortisol Diagnostic Assay (76 singlet tests): £189 per Kit (€264.60)   So that's £2.35 per singlet test (€3.28)   YES! £2.35 (€3.28) per singlet Test   Talk to our European support team [email protected] +44 (0) 1638 782619 ______________________________________
