BioCheck from 20/20 Gene Systems is a bio-hazard detection kit. Although the kits were created specifically to test for anthrax, BioCheck can detect other protein-containing agents, such as ricin or botulinum toxin. The kit is simple to use, requires no instrumentation, and provides accurate results within minutes. Each kit consists of a tray, two test tubes, and two wetted swabs. Color change in the test tubes indicates positive results. Inexpensive training kits are also available.
