But there's hope: within the late 1990s biologists in the College of Singapore realised that a artificial alternate can be created inside a lab by cloning a molecule inside the crab blood. This genetically engineered protein is termed Recombinant Factor C, or rFC.
Meanwhile, efforts to know and perhaps relieve some of the sub-lethal consequences of your bleedings are underway.
It's also arguable medicine producers aren't the biggest problem going through horseshoe crabs: in America a lot of far more are killed for fishing bait and lots are having difficulties in Asia since their habitat is disappearing.
