Biotech can save the horseshoe crab

NEW: For decades, drug manufacturers have relied on the blood of the horseshoe crab to make vaccines safe. But a synthetic substitute can replace this practice, and just in time—when 14 billion doses of Covid-19 vaccines are needed.

Up to 500,000 horseshoe crabs are bled every year to make an endotoxin test called Limulus amebocyte lysate (LAL). But there is a synthetic alternative to this test called recombinant factor C (rFC) that is more sustainable and more consistent. Adoption of rFC is possible, today.

Turning the tide for horseshoe crabs

In 2018, Revive & Restore hosted a press event in Cape May, New Jersey, a location renowned for its concentrations of shorebirds and breeding horseshoe crabs. The event was joined by the state’s First Lady Tammy Murphy, the New Jersey Audubon Society, and representatives of Eli Lilly to announce research findings that were soon to be published in PLOS Biology.
