      It’s an anticoagulant and can detect the smallest traces of endotoxins in medicine. I’m sure I’m missing some details but there are some great medical journals that detail the process and help explain why it’s $60,000 a gallon.

        It is not an anticoagulant, quite the opposite actually. The blood (limulus amoebocyte lysate) will coagulate at the slightest hint of gram-negative bacteria and their endotoxins.

        It’s most likely a defense mechanism against bacterial infections.

        It’s widely used in medicine to check for bacterial contamination of injectable pharmaceuticals.

          Discoveries like this always makes me wonder, who had the idea to try it and why

          Woah. Are horseshoe crabs like other crustaceans in that they eat pretty much anything including/mostly detritus?

          If thats the case, than how would it be beneficial to have blood that coagulates so easily?

          Wouldn’t every meal lead to a crab version of a stroke?

            Horseshoe crabs are not crusteceans, they are early chelicerates.

            They have an open circulatory system, where the blood (heamolymph) freely spills out of the arteries into surrounding tissues, so a small clot probably wouldn’t cause issues. Think of it like a cyst, sometimes if an infection can’t be removed by the immune system, your body will just enclose it in a capsule, so it can’t spread.

        Where can someone find these horseshoe crabs?

        And are they able to be bred in captivity?

        Pls respond fast, I’m already driving to home depot to buy the largest above ground pool they have.

      The blood contains a coagulent which clots in the presence of bacterial toxins. It is extracted and used to ensure that medical equipent and stuff such as vaccines are sterile and safe.

      The main use is to detect how much endotoxins (proteins that cause our immune system to react) are present in a sample. This is important because we often use bacteria/fungus/yeast to produce medicine and then remove the microorganism from that medicine. This checks for anything left behind in that process, far more sensitive than any other test or machine can do.

      If it wasn’t for horseshoe crab blood, creating medicine that is safe for injection would be a lot harder and potentially more dangerous.
