R&D Systems is now offering two new Parameter™ Assay Kits designed to measure the levels of Testosterone (Catalog # KGE010) or LTB4 (Catalog # KGE006B ) in cell culture supernatants, serum, or plasma samples. In addition, a new human Quantikine TREM-1 ELISA (Catalog # DTRM10B ) is now available for use with cell culture supernatants, serum, plasma, or saliva. Both the Testosterone and LTB4 Parameter Kits are competitive binding immunoassays, while the TREM-1 Kit is a sandwich ELISA. Parameter and Quantikine Kits are fully validated, produce a high signal to noise ratio, and allow for excellent reproducibility. ■Antibodies ■ELISAs/Assays ■Recombinant & Natural Proteins |
