Endotoxin assay kit lonza

Endotoxin Detection Methods for Pharmaceuticals and Medical Devices Introduction Bacterial endotoxin is a key safety and quality issue for the pharmaceutical and medical device industry. Its' importance lies in the fact that it is pyrogenic. Pyrogens are a diverse group of compounds defined by their ability to cause a rapid rise in core temperature when introduced into the bloodstream.

Endotoxin assay kit lonza

Store all reagents at degree C. Sample Preparation We suggest pre-experimenting with neat undiluted samples, 1: Please avoid diluting your samples more than 1: If the expected concentration of the target is beyond the detection range of the kit, please contact our technical support team Product Note Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved.

If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order.

We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual. Other Notes Small volumes of EDT elisa kit vial s may occasionally become entrapped in the seal of the product vial during shipment and storage.

EAA™ Endotoxin Activity Assay

Certain products may require to ship with dry ice and additional dry ice fee may apply. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing EDT, with an estimated sensitivity of 1.

Endotoxin, a confounding contaminant derived from bacterial products, promotes cell signal transduction in human and other vertebrate species, like guinea pig cells through TLR4.

Quantitative endotoxin testing or determination of an endotoxin free protein purification fraction is accomplished by comparing sample results to included standard curve reagent.The endotoxin activity assay (EAA, Ref.

34) is a rapid chemiluminescent immunodiagnostic test kit. EAA is a very interesting method for plasma endotoxin detection, although this is not a limulus test.

A very sensitive assay for detecting the presence of endotoxin is the Limulus amebocyte lysate (LAL) assay, using aqueous extracts of amebocytes from the horseshoe crab. Very low levels of endotoxin induce a clotting cascade of several enzymes.

Alternative Endotoxin Testing Methods. Horseshoe crabs have played a role in human health since the s. LAL and TAL methods have changed since the first gel clot test, however the last advancement came in the s when a chromogenic substrate was added to the LAL/TAL chemistry.
