Endotoxins (type of pyrogen), are lipopolysaccharides present in the cell walls of gram-negative bacteria. Pyrogens are fever-inducing substances that can be harmful or even fatal if administered to humans above certain concentrations.
The LAL (limulus amebocyte lysate) Assay is an in vitro assay used to detect the presence and concentration of bacterial endotoxins in drugs and biological products.
LAL test ensures that injectable therapeutics are safe for human use.
Abiolabs performs the Kinetic Chromogenic LAL Assay, a sensitive colorimetric assay that can detect endotoxin levels in solutions at concentrations as low as 0.05 Endotoxin Unit/mL.
Water can also be a source of pyrogens. Therefore, it may be important to perform endotoxin testing to routinely monitor water systems.
