Effects of blood extraction on the mortality of Malaysian horseshoe crabs (Tachypleus gigas)

Horseshoe crabs provide the important biomedical products, Limulus Amebocyte Lysate (LAL) and Tachypleus Amebocyte Lysate (TAL), which are produced by lysing the blood cells (amebocytes) using endotoxin-free distilled water. LAL/TAL is used to detect and quantify lipopolysaccharide (endotoxin), an i...
