A fast, sensitive, specific and accurate detection method to determine active infection by Bacillus anthracis in plasma has been developed at List Biological Laboratories.

Bacillus anthracis is regarded as a major biological warfare threat. The inhalation form of Bacillus anthracis infection can kill quickly.  While antibiotic treatment can clear the bacterium from the host, if diagnosis is delayed, the toxin, which is rapidly produced, may already be present in lethal amounts. There is a critical need for a rapid, accurate, sensitive and simple assay to determine whether infection has occurred thereby allowing immediate treatment.

Anthrax Detection Method

Anthrax lethal factor (LF), an endopeptidase, is present in blood in the early stages of the infection.  The use of peptidic substrates in plasma is problematic due to the presence of other proteases and the likelihood of nonspecific cleavage of the substrate.  A fluorescently labeled peptide substrate, MAPKKide Plus, Prod #532, which is not cleaved by plasma proteases and thus is specific for LF has been designed. The LF is enriched by capture from plasma using an LF antibody-coated microtiter plate, and the captured LF is then exposed to the fluorescent substrate.  The amount of cleaved peptide substrate is determined by HPLC with fluorescence detection. Concentration of the LF using the antibody-coated plates allows for the detection of 5 pg LF/ml of neat plasma after 2 hours of incubation.  Alternately, the MAPKKide Plus may be added directly to diluted plasma and cleavage monitored by an increase in fluorescence as a function of time using a fluorescent microplate reader.  The limit of detection by this simpler method is 1 ng LF/ml of plasma after 5 hours of digestion.  Both methods can be confirmed by analysis of the reaction as a function of time.  These methods are described in the poster Sensitive Detection of Anthrax Lethal Factor in Plasma Using a Specific Biotinylated Fluorogenic Substrate.

What’s Next for Anthrax Detection Method

We are currently working with a biotinylated form of MAPKKide Plus to enhance the sensitivity of the simpler method using the fluorescent plate reader rather than HPLC.

List Labs will be attending the 54th annual Interagency Botulism Research Coordinating Committee (IBRCC) this year from October 27-30th. The conference will be held in Ellicott City, MA at the Turf Valley Resort and Conference Center. This international forum presents state-of-the-art research on botulinum toxin and the deadly disease of botulism. This important conference provides the opportunity for federal and non-federal agencies to coordinate in the effort against botulism in all of it’s forms.

The following List Labs employees will be attending the conference:

• Karen Crawford, President
• Nancy Shine, Director, Research & Development
• Max Purro, Ph.D Scientist
