Technical Information POWDER SCREENING TEST KIT • Save resources and time and reduce citizen concern over false alarms The BioCheck Powder Screening Kit provides a simple screen for possible biological threat by indicating the presence of protein, which is common to virtually all BWA microbes and bio-toxins. • When used in combination with the HazMatID Ranger it allows responders to rule out possible presence of BWAs in suspicious powder situations The kit includes a highly sensitive and protein-specific reagent that changes to a purple color in the presence of protein. Feature highlights • Simultaneously screens for the possible presence of multiple agents (anthrax, ricin, botulinum toxin) • Laboratory proven to detect Anthrax, Plague, and Ricin • Results in 5 minutes • Easy to use and economical Used in conjunction with other biological threat assessment technologies, BioCheck provides a fast, easy-to-use preliminary screen for the presence or absence of protein, associated with BWAs. The BioCheck kit also includes a pH test to help identify possible presence of chemical interferents compounds that might compromise the reliability of the protein screen or other BWA tests such as lateral flow immunoassays, fluorescent dye microbe screens and PCR assays. The BioCheck is backed by first rate service, training and support to ensure optimum product performance.
