Limulus Amebocyte Lysate

Limulus Amebocyte Lysate (LAL) is a test derived from the blood of horseshoe crabs, used to detect bacterial endotoxins in medical equipment, pharmaceuticals, and vaccines. Endotoxins are harmful substances produced by certain bacteria. When LAL comes into contact with these toxins, it reacts by clotting or changing color, signaling the presence of contamination. This test is highly sensitive and reliable, helping ensure products are safe for human use by identifying dangerous bacterial contaminants before they reach patients.
