Multiplex sequencing of up to 8 Oncomine Myeloid Research Assay GX samples (8 DNA+ 8 RNA) per lane on a GX5 Chip can be performed in a single run. There are 4 lanes on the GX5 Chip, so 32 total samples (32 DNA+ 32 RNA) can be run on one GX5 Chip (8 samples per run).
The Oncomine Myeloid Research Assay GX (Cat. No. A47857) includes the 2-pool DNA panel, the 1-pool RNA panel, Genexus Strip 1, and Genexus Strip 2-AS. The DNA panel is provided in two packs of 8 tubes (4 tubes of Myeloid DNA Pool 1 and 4 tubes of Myeloid DNA Pool 2 per pack). The RNA panel is provided in one pack of 8 tubes (Myeloid RNA Pool 1). Each primer pool in the panel is provided in pairs of tubes, where each tube pair contains one tube with primers in position 1 and one empty uncapped tube in position 2. Three 8-strip packs of the Genexus Strip 1 and Genexus Strip 2-AS (24 total of each strip) are provided with each kit.
The contents of each Oncomine Myeloid Research Assay GX kit are sufficient for up to 32 samples (32 x 3‑pool reactions: 32 x 2‑pool DNA reactions and 32 x 1‑pool RNA reactions).
The Oncomine Myeloid Research Assay GX includes 3 pools of Ion AmpliSeq oligonucleotide primers (a 2-pool DNA panel and a 1-pool RNA panel).
The Oncomine Myeloid Research Assay GX targets key genes and fusions associated with major myeloid disorders, including acute myeloid leukemia (AML), myeloid dysplastic syndrome (MDS), myeloproliferative neoplasms (MPN), chronic myeloid leukemia (CML), chronic myelomonocytic leukemia (CMML), and juvenile myelomonocytic leukemia (JMML). The DNA panel comprises 40 key genes while the RNA panel includes a broad fusion panel of 29 driver genes, enabling detection over 600 unique fusion isotypes. See flyer for gene targets (https://assets.thermofisher.com/TFS-Assets/CSD/Flyers/Oncomine_myeloid_assay_gx_flyer.pdf).
The Oncomine Myeloid Research Assay GX is a comprehensive targeted next-generation sequencing (NGS) assay designed for sensitive detection of myeloid disorder-associated DNA mutations and fusion transcripts in blood and bone marrow samples.
The capacity of the GX5 Chip varies depending on the sample type:
- For plasma cfTNA samples, the workflow is configured to accommodate 1 sample per GX5 Chip lane (or 4 samples on a single GX5 Chip).
- For FFPE DNA+RNA samples, the workflow is configured to accommodate 4 samples per GX5 Chip lane.
- For FFPE DNA-only or RNA-only samples, the workflow is configured to accommodate 8 samples per GX5 Chip lane.
The maximum number of samples that can be analyzed per kit depends upon the type of analysis that you want to perform. Each kit provides the targeted pancancer panel and library reagents sufficient to perform up to 32 sequencing reactions on the Genexus Integrated Sequencer.
- Simultaneous DNA- and RNA-based variant analysis for up to 16 FFPE tissue samples (one DNA reaction and one RNA reaction per sample)
- DNA-only or RNA-only variant analysis for up to 32 FFPE tissue samples
- Cell-free TNA (cfTNA) variant analysis (combined DNA and RNA) for up to 32 plasma samples
For solid tumor samples, the optimal input amount is 10 ng with validated input in the range of 5-15 ng. For liquid biopsy samples, the optimal input amount is 20 ng with validated input in the range of 5-40 ng.
For optimal results, load 20 µL of input with a concentration of ≥0.67 ng/µL for FFPE DNA and FFPE RNA samples and 20 µL of input with a concentration of ≥1.33 ng/µL for cfTNA samples. If the concentration of the sample is lower than optimal, use as much input as possible for each reaction.

Oncomine Precision Assay GX is compatible with solid tumor samples (FFPE DNA or FFPE RNA) as well as liquid biopsy samples (cfTNA).
Oncomine Precision Assay GX is designed for the detection of biomarkers in genes such as EGFR, BRAF, KRAS, ALK, ROS1, NTRK, RET, HER2. The assay analyzes 78 variants, including mutations (45), CNVs (14), and fusion variants (19), across 50 key genes. Included are tumor suppressor genes such as TP53, cancer drivers, and resistance mutations. Content has been carefully curated to include all relevant targets and targets of emerging importance in precision oncology clinical research.
Oncomine Precision Assay GX (Cat. No. A46291) includes the following:
- OPA Pool 1 panel (Part No. A44350)
- Genexus Strip 1, quantity of 8 strips (Part No. A46812)
- Genexus Strip 2-HD, quantity of 8 strips (Part No. A46814)
- The OPA Pool 1 is provided in 8 pairs of tubes, where each tube pair contains one tube with forward (FWD) primers and one tube with reverse (REV) primers.
The Genexus Primer Pool Tubes kit contains 50 empty assemblies (2 tubes/assembly) of the custom tubes required to deliver primer oligos into the automated library preparation reaction. Each assembly is serialized for traceability and can be used with Ion AmpliSeq- and Ion AmpliSeq HD-based assays. Pipet an aliquot of panel primers from a custom panel or Ion AmpliSeq On-Demand Panel to run the assay on the Genexus Integrated Sequencer. The kit also contains a bag of 100 caps.
Note:
- Assays using Ion AmpliSeq chemistry have primer pools that are loaded in capped tubes in position 1 of the primer pool tube carriers. Empty uncapped tubes are loaded in position 2.
- Assays using Ion AmpliSeq HD chemistry have FWD and REV primer pools that are loaded in capped tubes in both positions of the primer pool tube carrier.

Remove the templating strips from their boxes in the refrigerator or freezer, and prepare them for loading in the sequencer.
- Genexus Strip 3-GX5 needs to equilibrate to room temperature for 30 mins.
- Genexus Strip 4 needs to thaw on ice for at least 30 mins. Keep the strips on ice until you load them in the sequencer.
Genexus Strip 3-GX5 contains magnetic beads in one or two positions, yellow or brown in color, that sometimes get trapped in the upper "keyhole" of the tube. Dislodge these beads from the keyhole before installing the strip in the sequencer. Use the following procedure for each strip:
- Invert the strip 3-4 times to dislodge beads that are trapped in the keyholes.
- To remove any remaining beads and liquid from the keyholes, grasp the strip at one end with the strip seal facing up, then swing the strip with a rapid, downward centrifugal arm motion, ending with a sharp wrist-flick.
- Grasp the strip at the other end, then repeat the centrifugal motion.
- Check tube positions for significant amounts of beads that are still trapped in keyholes, then repeat the centrifugal motion, if needed. It is acceptable if a few beads remain in the keyhole or on the tube wall, but most should be either in suspension or in a pellet at the bottom of the tube.
