BLUE BLOOD | Horseshoe Crab Harvesting and Extracting Blue Blood For Biomedical Research

Humans aren’t only donating their blood for the noble cause. We are grateful to these the weird, prehistoric horseshoe crab as these creatures involuntarily donate their blood every year for the survival of human race. Its blue blood is used in biomedical research to ensure that whatever that gets administered or implanted into the human body is free of possible bacterial contamination. A special chemical in the crab’s blood quickly clots in the occurrence of endotoxins, microbial byproducts that can be lethal, supplying a flawless natural test for purity. Blood of horseshoe crabs is playing a vital role in the development of COVID-19 vaccine due to this potential. When you give blood, you donate about 10 percent of your blood volume, but horseshoe crabs are drained (without the voluntary donation part) of about 30 percent of theirs. A lot of research has been done into creating an artificial substance that could be an alternate for the blood of the horseshoe crab. An artificial alternative to crab lysate (Chemical available in the blood), recombinant factor C (rFC), was accepted as a substitute in Europe, and a handful of U.S. drug companies also began using it.
