The PYROSTAR™ ES-F series of reagents are endotoxin-specific and specially formulated to be unreactive to (1→3)-β-D-glucan. In addition, these products are dual-purpose, meaning they are formulated to be used as eithera gel clot or a kinetic turbidimetric assay. They are available in a single-test or multi-test configuration.

These reagents require only one Certificate of Analysis (COA), regardless of whether they are used as a gel clot or kinetic turbidimetric assay. PYROSTAR™ ES-F/Plate requires a different COA. All reagent kits are matched with a specific Control Standard Endotoxin (CSE). These reagents work well with samples that have color or with samples that present difficulties in quantification by the KCA.
