Endotoxin ELISA Testing Service

Endotoxin ELISA Testing Service

Endotoxin is a glycocalyx attached to the outer leaflet of the outer membrane of gram-negative bacteria and is an important component of the outer membrane, consisting of lipid A, core oligosaccharides, and O-antigenic polysaccharides. Lipid A is the active and toxic center of endotoxin. Endotoxin is a toxic compound that can cause fever, microcirculatory disorders, endotoxic shock, and disseminated intravascular coagulation. Endotoxins are thermally stable, widely present in the environment, and easily contaminate biological products. Therefore, endotoxin assay is necessary for the biological and pharmaceutical industries. Creative Diagnostics provides accurate endotoxin ELISA testing for all manufacturing stages of biologics.

Testing Capabilities

We detect endotoxins released by the rupture of a wide range of gram-negative bacteria, including but not limited to E. coli, Salmonella, S. typhi, S. dysenteriae, etc.

Sample Types

The endotoxin is highly stable and for sending the sample you have the following options.

1. Send the sample to be tested directly under frozen condition.

2. Send the sample after simple processing.

3. Send the endotoxin after extraction.
