What’s The M-TRAP®?

M-TRAP® is a Patented air sampling cassette developed specifically for the rapid capture and analysis of airborne mold spores using state-of-the-art DNA analysis.  It embodies the next generation of capture technology for residential and occupation mold exposure assessment.  The M-TRAP® excels where spore trap and agar impaction falls short — spore capture efficiency and turnaround time.

Molecular Entrapment White paper

Three years of R&D by Assured Bio Labs has produced a novel, patented breakthrough in biologically active capture substrates called molecular entrapment.  Molecular entrapment employs a biologically active compound that is bonded to an inert, three dimensional fibrous substrate.  An adhesive protein molecule attaches to spores that enter the substrate. The protein significantly alters a spore’s inertial properties leading to entrapment.  The molecular entrapment substrate is enclosed in a high quality, chemical-resistant polypropylene housing. M-TRAP® eliminates the difficulties associated with mold sampling and result interpretation.

  • No overloading or particle bounce
  • Enhanced capture efficiency, especially for Stachybotrys
  • Removes group bias with species ID of Aspergillus/Penicillium-like molds
  • High-fidelity analysis reduces uncertainty of measurement
  • Eliminates inter-analyst variation

M-TRAP® allows for a true outdoor to indoor species comparison. Its level of reliable detail gives the investigator a degree of insight that until now has been out of reach of the indoor air quality industry.

M-TRAP® is Easy to Use

M-TRAP® was designed with simplicity in mind. Anyone familiar with the most common air sampling pumps on the market will be able to use it.

Analytical Method

Mold Specific Quantitative Polymerase Chain Reaction (MSQPCR) is a variation of standard PCR analysis developed by the U.S. Environmental Protection Agency for precise detection and quantification of mold spores to species. Our patented, biologically active capture substrate is DNA friendly and specifically designed to maximize the high-fidelity detection ability of MSQPCR. In essence, the different types of fungal DNA present in a sample are individually replicated and fluorescently tagged until a measurable amount of light is emitted. The point in time that the light emissions become measurable by a highly sensitive optics system directly correlates to the identification and quantification of the mold spores present. MSQPCR uses fluorescent probe chemistry to detect the 36 most common molds found indoors, as identified by the Healthy Homes Initiative Study conducted by the EPA and HUD. These DNA-based technology results are 99.9 percent accurate.

Rapid and Versatile Sample Collection

The M-TRAP® air sampling cassette was designed with ease of use in mind — a boon to anyone who routinely collects spore traps for direct examinations. Utilizing the provided adapter, M-TRAP® may be connected via ½” tubing commonly used with air sampling pumps that are currently on the market. The pump’s flow rate should be set at 15 liters per minute prior to use and the sample should be collected for 10 minutes yielding a sample volume equivalent to 150 liters of air. Resultant data interpretation is a snap: It is presented in total spores per cubic meter of air. Just as with current direct examination technology, an outside reference sample is recommended for baseline comparison.
