key features
Rapid Multiplexed Testing
Patented D3 Array technology is fast, cost effective, easy to use, and highly multiplexed with over 100 targets in a single reaction—delivering highly specific, sensitive and accurate results.
• Novel 3D probe network, in solution, makes for faster and more specific binding
• Speed – fast reaction times
• Realtime hybridization
• Cost effective vs serial qPCR determinations and NGS
• Much faster than NGS
Sensitive & Specific
When multiple targets, speciation or variant detection is needed, the D3 Array provides far more utility than qPCR testing and far less time and cost than NGS. Gain economies and flexibility without compromising accuracy.
• No steric hindrances
• Enhanced access to probes
• Asymmetric endpoint PCR
• Increased hybridization affinity
• Single gene copy sensitivity
Broad Applicability
D3 Array technology is driving rapid identification and quantitation of target pathogens and other known targets (including cancer) across human diagnostics (EUA & RUO), food processing and cannabis testing, with new applications coming to market in 2023.
• Highly multiplexed array
• 100+ targets per reaction
• Diverse sample types
• Broad application in Food, Agro and Human Diagnostics (EUA & RUO)
The D3 Dynamic Dimensional Detection Array at Work
With enhanced probe binding, single gene copy sensitivity, and competitive economies and time-to-result, the D3 Array delivers advantages that promote better outcomes.
RUO assays addressing bloodborne illnesses and UTI infections are expected in 2023, with applications for cancer screening down the road. Learn more »
PathogenDx introduced its first food safety assay without the need for enrichment in 2020, supporting Preventive Environmental Monitoring (PEM) programs, and continues to apply its D3 Array to the specific requirements of poultry producers and food processors. The latest assay, SeroX, identifies the vast majority of Salmonella serotypes that cause harmful infections in a single test and in a single shift. Learn more »
PathogenDx partners with over 120 laboratories in 36 states to support regulatory compliance and integrity in legal Cannabis testing. The D3 Array powers the industry’s most complete testing platform, with assays for detection and quantitation of regulated pathogens, environmental testing and plant viruses such as Hop Latent Viroid. In addition, the recently introduced Octa™ AutoPrep Station simplifies and automates the Cannabis lab workflow and reduces skilled labor. Learn more »
