ENDOTOXIN DETECTION
Make critical decisions with clearer evidence.
ClearSignal is a product concept for teams that test process samples, raw materials, and finished products for bacterial endotoxin. It connects preparation, measurement, controls, and reporting in one coherent workflow.
The result is not just a number. It is a traceable path from sample identity to analytical interpretation—so reviewers can understand how the answer was reached.

THE TARGET
What is endotoxin?
Endotoxins are lipopolysaccharides associated with the outer membrane of Gram-negative bacteria. Testing measures their presence in samples where control of pyrogenic contamination matters.

RESEARCHER FAQ
Questions before you send a sample.
Start with the essentials, then submit your sample details for a matrix-specific laboratory review.
01What is endotoxin, and why is it tested?
Endotoxins are lipopolysaccharides associated with the outer membrane of Gram-negative bacteria. Testing helps researchers assess contamination against the limit established for their material and intended use.
02What types of samples can be tested?
Typical samples include biologics, cell and gene therapy materials, vaccines, medical-device extracts, raw materials, and water. Each matrix is reviewed for method suitability.
03Which endotoxin testing method is used?
ClearSignal supports a recombinant Factor C endpoint fluorescence workflow. The laboratory confirms that the method is suitable for the submitted matrix and intended use.
04How much does Endotoxin cost?
The standard endotoxin test costs $375.00 USD per sample.
05How much sample do I need to provide?
The required amount depends on the sample matrix, anticipated dilution, controls, and whether repeat testing may be needed. Submit the available quantity and unit so the laboratory can confirm requirements before shipment.
06How should samples be labeled and prepared?
Give every sample a unique ID and document its matrix, product or lot, process stage, storage condition, and quantity when applicable. Packaging and temperature requirements should be confirmed before shipping.
07How is sample interference handled?
The laboratory evaluates inhibition or enhancement using appropriate controls and dilution studies. Any dilution must remain within the sample’s maximum valid dilution.
08What information should accompany my testing request?
Sample names are all that is needed, but you can also add project name, and testing purpose.
09How long does endotoxin testing take?
3-5 days
10What information is included with the result?
The result will report endotoxin concentration in endotoxin units per milliliter (EU/mL).
11Where do I send my samples?
Samples can be sent to 555 Jackson Dr, Baltimore, MD 21208.
12Are plasmid samples okay to send?
Yes, we routinely test aqueous samples containing plasmid.
