ELISA Kits

Enzyme-linked immunosorbent assays (ELISAs) are a workhorse application for cell biologists because they measure secreted proteins, growth factors, hormones and small molecules. Biomarker researchers are also high on the list of ELISA users as liquid biomarker discovery is an aspirational, yet crucial prerequisite for therapeutic interventions across disease research areas, from neurodegeneration to cancer. R&D Systems, a Bio-Techne brand has a broad array of ELISA kits that are optimized for each investigator’s specific circumstance. Some investigators want to accurately and precisely quantify an analyte.  For these investigators, the R&D Systems™ Quantikine ELISA is the best bet. These ready-to-use ELISAs are the most highly cited on the market. They are rigorously validated during the manufacturing process, using a master calibrator. Other investigators require the highest sensitivity. The Quantikine High Sensitivity (HS) ELISA detects analytes at the single femtogram level. Those that want to save time can rely on Quantikine QuicKits, which can be completed in 90 minutes. “Do-it- yourselfers” are able to build their own sandwich assay using DuoSet ELISA development systems. Investigators involved in a global collaboration might put a premium on a hands-off, automated ELISA that conserves sample and time while minimizing user error. The Simple Plex immunoassay featuring Ella is the ideal platform where real-time data and consistency across users and geographies is paramount. Clinicians may require in vitro diagnostic assays for use as part of a therapeutic workflow. In this instance, Quantikine IVD ELISAs are 510(K) approved and ready to use. Quantiglo Chemiluminescent Sandwich ELISAs are another option for investigators that require a broader dynamic range than colorimetric immunoassays. Parameter Colorimetric Competitive ELISAs are ideal for measuring small molecules like cAMP, cGMP and NO. These assays also quantify hormones such as estrogen and testosterone.
