About this opportunity
The Department of Agriculture Animal and Plant Health Inspection Service is issuing a sole-source procurement notice for 10 kits of the ChapterDx PomePlex-26 NGS assay, a total small business set-aside, with responses due by September 7, 2026 at 12:00 PM CST. ChapterDx is identified as the sole supplier of a 26-virus NGS assay formatted for 96-sample diagnostics compatible with the Service's established laboratory workflows. Each kit provides reagents sufficient to conduct diagnostics on 96 individual samples across 26 targeted plant pathogens affecting pome trees. The acquisition supports the Plant Protection Act Section 7721 FY26 project "Implementing a largescale assay for simultaneous diagnostic of all pome tree viruses/viroids in certification programs" within the Plant Germplasm Quarantine Program, replacing laborious individual PCR diagnostics for each pathogen target with simultaneous multi-pathogen testing. The ChapterDx assay requires minimal sample input (2 microliters) when applied with NGS-based techniques. Todd K. Bierl, Major Program Contracting Officer in the Emergency Acquisition Marketing and Regulatory Program Business unit (APHIS Acquisition Branch), administers the procurement.
Notice text
Sole Source Notification
Acquisition of 10 kits of the ChapterDx PomePlex 26
The Plant Germplasm Quarantine Program routinely screens for a battery of 26 viruses and viroids through individual PCR diagnostics for each of the 26 targets, which is very laborious and time consuming. The ChapterDx PomePlex 26 allows testing all 26 viruses and viroids all at once in a single tube reaction.
This technology will be used as part of the work plan approved for a project awarded by the Plant Protection Act PPA7721 Spending plan FY26 titled “Implementing a largescale assay for simultaneous diagnostic of all pome tree viruses/viroids in certification
programs”. The list of awarded projects can be found at Plant Protection Act Section 7721 Fiscal Year 2026 Spending Plan. Each of the 10 kits requested for purchasing provides enough reagents to conduct diagnostics on 96 individual samples across the 26
targeted plant pathogens.
ChapterDx is the only company that sells a 26 NGS assay ready for sequencing in a 96 sample format with as little as 2ul of samples when followed NGS-based techniques. Our laboratory conducts plant pathogen diagnostics of imported germplasm that are compatible with all our established workflows for accurate diagnostics of plant pathogens using the ChapterDx Pome Plex 26 NGS assay.
