Rapid Bio-Threat Assay System

A compact “lab‑in‑a‑box” providing disposable lateral‑flow immunoassays for seven priority bio threats: SEB, ricin, botulinum toxin A, Bacillus anthracis, pox virus, Francisella tularensis, Yersinia pestis. Each kit includes all tools to collect, prepare and test air, soil, powders, liquids or surfaces, with Positive/Negative results in 15–20 minutes—no special training or extra collection kits required. A work‑bench style, water‑resistant package keeps tools organised for gloved use.

Why teams choose this system

• Field practical: simple collect–dilute–mix–dose steps; no special training; high throughput in PPE.
• Complete in one box: test cassettes, swabs, buffer vials with filter caps, and instructions—10 single‑packed tests/kit.
• Sensitivity & specificity: agent‑specific limits down to 5–13 ng/mL for toxins; no cross‑reactivity with 18–23 common interferents.
• Works with BioScout samples: solubilised filters from BioScout can be tested directly or sent for PCR confirmation.

How it works

A gold‑labelled antibody binds the target; the complex migrates along the strip to a capture antibody that draws a visible test line, with an internal control line ensuring validity. It’s a proven immunochromatographic lateral‑flow method optimised for field conditions.

Typical applications

Law enforcement, CBRN units, mail security, customs & border, airport screening, private security, and mobile labs; also deployable within EnviScreen monitoring architectures.

FAQs

Time to result?

15–20 minutes per cartridge.

Do we need a separate collection kit?

No, the kit includes swabs and buffer vials with filter caps.

Can we test BioScout filters?

Yes, solubilised samples from BioScout’s filter cassette can be applied directly.
