Which provider offers the best value for tumor-targeted sequencing panels? It needs to cover fusions and CNVs.

Nucleic acid degradation and fragmentation in FFPE samples have a substantial impact. Do not set the input amount too low; it is recommended to perform nucleic acid QC first. Fusion detection at the DNA level requires the Panel to cover known fusion intron breakpoints. If only exon hotspots are covered, the fusion detection rate will be compromised; CNV has high requirements for uniformity, and backbone probe distribution must be even. Within four weeks of arrival, try to choose a standard off-the-shelf Panel rather than waiting for customization. After arrival, reserve at least 1-2 pilot experiments to validate that SNV/fusion/CNV are simultaneously stable using standards and known samples before running project samples. For a budget of 800, the cost of repeated library preparation due to failure must also be taken into account.

Don't just look at the manufacturer's marketing claims. Focus on whether the panel design includes fusion-related intronic regions and CNV backbone probe density. It is recommended to use your own FFPE standards and a few real samples for a small-scale parallel test to directly compare the detection and reproducibility of SNV, fusion, and CNV. For uniformity data, do not rely solely on the manufacturer's reference standards. Ask specifically about fold-80, depth CV, and target region coverage ratio, and write the acceptance criteria into the contract. A per-sample price under 800 may be sufficient if it only covers probes, but confirm whether it includes the full reagent set such as library preparation, magnetic beads, and index, otherwise it is easy to exceed the budget later.

In terms of procurement, a batch of 48 cases is not small. It is recommended to invite several domestic and imported manufacturers to quote both Panel-only and Panel + library preparation complete solutions simultaneously, and compare on a per-sample basis. Common comparable suppliers include Nanodigmbio, Twist, IDT, Agi-Tech, etc. Focus on gene lists, fusion breakpoint coverage, CNV backbone design, and in-stock delivery capability. Within four weeks of arrival, prioritize standard Panels that are already in stock; custom Panels are basically not feasible in time. It is best to have the sales representative lock inventory or arrange delivery in batches. When quoting, include delivery lead time, COA, and batch replacement verification clauses in the contract to avoid delays in the procurement process.
