Product Overview
Gel Clot LAL (PYROGENTTM) provides a simple positive/negative result and is most often mentioned in pharmacopeial monographs as the official referee test. Lonza’s PYROGENTTM Gel Clot LAL Assay is a qualitative LAL test for Gram-negative bacterial endotoxin. The gel clot assay is run in tubes that are placed in a water bath or dry heat block at 37°C. After a one-hour incubation period, the tubes are flipped 180°. A firm clot that stays in the bottom of the tube indicates a positive reaction. If liquid flows down the side of the tube, the result is negative for endotoxin. PYROGENTTM Gel Clot LAL Assay requires depyrogenated 10 x 75 mm glass reaction tubes to run the assay.

Troubleshooting Guide - Testing Oil Solutions with PYROGENT™ Gel Clot LAL Assay
Endotoxins, due to their lipid character, tend to remain associated with oils and do not readily enter the aqueous phase of water-oil mixtures. This Tech Tip describes the use of a dispersing agent, PYROSPERSE™, to allow for dissociation of the endotoxin from the oils and for subsequent detection of endotoxin in the aqueous phase by the PYROGENT™ Gel Clot LAL Assay. -
