Limulus Amebocyte Lysate Assay (LAL)

The LAL assay is the most sensitive and specific means available to screen medical devices, raw materials and media for the presence of harmful levels of endotoxin.

Embryotech Laboratories offers two types of LAL assay:

Gel-Clot LAL

The Gel-Clot LAL assay is based on a biological enzyme reaction wherein the presence of specific endotoxin levels produces an opaque gel. A firm gel is formed if the concentration of endotoxin exceeds the reagent labeled sensitivity.

Kinetic Turbidimetric LAL

The Kinetic Turbidimetric LAL assay is a quantitative, kinetic assay for the detection of bacterial endotoxin. In the presence of endotoxin, the lysate will begin to gel, resulting in turbidity (cloudiness) of the solution. The time required for the change is used to determine the amount of endotoxin present. The maximum sensitivity is 0.001 EU/mL

Our technicians take the upmost precautions while performing endotoxin testing to prevent any contamination of the products tested.
