Recombinant Factor C (rFC) Endotoxin Detection Kit

Animal-free endotoxin test: recombinant Factor C detects bacterial endotoxin by endpoint fluorescence — no β-glucan interference, 0.005–5 EU/mL range, results in 1 hour at 37 °C. Validated to EP 11.0 and USP <1225>/<86>.

Overview

Overview

Every LNP formulation destined for injection must clear endotoxin testing before release. This kit does it without horseshoe crab blood: recombinant Factor C (rFC) recognises bacterial endotoxin and cleaves a fluorogenic substrate — the stronger the signal, the higher the endotoxin load. Unlike traditional LAL assays, rFC contains no Factor G and is not fooled by β-glucans, so false positives are rare and batch-to-batch consistency is high. It is the direction global regulators and the industry are moving in.

Samples and applications

Injectables, biologics, infusion cells, medical devices and cell culture media — plus in-process control of raw water, intermediates and finished product. Especially suited to samples containing β-glucans that trigger false positives in traditional LAL assays, and to LNP / mRNA release testing prior to animal administration.

Key features

  • No β-glucan interference — no Factor G in the kit, unlike LAL reagents
  • Sensitive and wide-ranging — quantification down to 0.005 EU/mL
  • Fast — results in about 1 hour, handling comparable to chromogenic LAL
  • Traceable — endotoxin standard traceable to USP reference material
  • Animal-free and supply-stable — recombinant production, consistent between batches, aligned with global regulatory direction away from animal-derived reagents

Notes

  • Requires a fluorescence microplate reader capable of 380 / 440 nm, plus endotoxin-free tips and glassware (the kit includes one endotoxin-free black plate). This is an instrumental readout assay, not visual judgement.
  • Catalogue numbers, COA and the full validation report are confirmed at enquiry.
  • For Research Use Only. Not a drug and not a diagnostic reagent; supplied exclusively for research applications.
  • Certification documents available on request and verifiable by certificate number. FOB pricing, MOQ and lead time quoted at enquiry.
