This utilises the coagulative properties of Atlantic horseshoe crab Limulus polyphemus blood to detect endotoxins linking this immunologically unique and ancient species to the global supply chains of modern health and medicine. Their blood is blue because they use copper as a carrier for oxygen while humans use iron as a carrier of oxygen in their red blood.
The Blood Of The Crab
Crab blood amebocytes can coagulate around as little as one part in a trillion of bacteria the equivalent of a grain of sand in a pool and the reaction takes less than an hour in contrast to more than two days for mammal blood.

Hundreds of thousands of horseshoe crabs Limulus polyphemus are bled each year to produce a substance called Limulus Amebocyte Lysate LAL. Standard practice is to remove 30 of the crabs blood and then return them to the water but 30 of these crabs never make it through the process. The price of horseshoe crab blood is also unbelievably high at 15000 per quart making it an expensive resource.

LAL is used to test intravenous drugs and medical equipment for the presence of bacteria and endotoxin a poison found in many bacteria. And horseshoe crab blood is the only thing humans can find anywhere.
A protein in the blood called Limulus Amebocyte Lysate LAL is used by pharmaceutical and medical device manufacturers to test their products for the presence of endotoxins bacterial substances that can cause fevers and even be fatal. An extract in the crabs blood cells chemically reacts to harmful stuff and scientists use it to test if new medicines are safe. The current global health crisis.
Horseshoe crab blood is an essential element in testing the safety of new drugs and vaccines. Because of this these crabs may have an important role to play in vaccine development. Horseshoe crabs blue blood is harvested by the biomedical industry for testing of drugs and medical devices.

Horseshoe crab blood and rFC are both used to screen injectable drugs for the presence of toxic contamination.
When those cells meet invading bacteria they clot around it and protect the rest of the horseshoe crabs body from toxins. The medical industry uses 600000 horseshoe crabs for their blood every year. Safety tests using horseshoe crab blood is currently the industry standard.
