Move Beyond LAL

This infographic compares traditional Limulus Amebocyte Lysate (LAL) testing with recombinant Factor C (rFC), focusing on sustainability, reliability, and supply-chain resilience. It shows how rising biopharma demand is placing increasing pressure on horseshoe crab populations, with wild harvesting impacting biodiversity and creating natural limits on supply. These constraints introduce risks around production continuity and availability. From an operational standpoint, LAL testing can be affected by β-glucan interference, biological variability between batches, and cost fluctuations linked to harvest cycles.

In contrast, rFC is presented as a fully synthetic, animal-free alternative that removes dependence on horseshoe crab populations while enabling scalable, controlled laboratory production. This supports greater supply stability and reduces environmental impact. Scientifically, rFC delivers high consistency and precision, supported by strong comparability and validation data, making it a robust option for modern endotoxin testing.
