WebRecombinant Factor C (rFC) is non-animal-derived reagent used to detect bacterial endotoxins in pharmaceutical products. Despite the fact that the reagent was first commercially available nearly 15 years ago, the broad use of rFC in pharmaceutical industry has long been lagging, presumably due to historical single-source supplier concerns and … Weba proenzyme, rFC becomes catalytically activated by trace levels of endotoxin. The resulting activated rFC hydrolyses a synthetic substrate to form a quantifiable product, which measures the level of endotoxin. Afluorimetric assay for endotoxin uses rFC zymogen, which, on activation by endotoxin, hydrolyses a fluorogenic substrate such as Boc ...

WebAn extract of the horseshoe crab's blood is used by the pharmaceutical and medical-device industries to ensure that their products, e.g., intravenous drugs, vaccines, and medical devices, are free of bacterial contamination. No other test worked as easily or reliably for this purpose—until now. WebRecombinant Factor C (rFC), similar to the native Factor C, is activated by endotoxin. In the rFC test method, branded PyroGene™ by Lonza, activated rFC cleaves a fluorogenic substrate and the fluorescent signal is monitored and analyzed to quantitate endotoxin content.
