The PR2110-S is the trial / sample-size SKU of the Accuris qMAX First Strand cDNA Synthesis Flex Kit family — 5-reaction pack for first-use evaluation of the 4-tube Flex Kit format before committing to the production-scale packs (PR2110-50 at $113 / PR2110-200 at $455). At $13 list price ($2.54 per reaction), the sample SKU enables labs to validate the high-concentration RTase + low-input RNA workflow on their specific RNA template.
For complete chemistry rationale (4-tube format, 200 U/µL RTase, 10 pg – 2.0 µg RNA input range), see the PR2110-50 parent page.
Key Specifications
| SKU | PR2110-S |
| Type | Sample / trial pack — qMAX First Strand cDNA Synthesis Flex Kit |
| Pack quantity | 5 reactions |
| RTase concentration | 200 U/µL (high) |
| RNA input range | 10 pg – 2.0 µg |
| Per-reaction cost (sample) | $2.54 |
| Sister sample SKU | PR2100-C-S (qMAX cDNA Synthesis Kit sample, 5 rxn, $20) |
| Production-scale follow-on | PR2110-50 ($113), PR2110-200 ($455) |
| List price | $13 |
Sample-vs-Sample Pricing — Flex Kit Cheaper
The two cDNA synthesis sample SKUs are price-differentiated to reflect the per-reaction cost differential between the kit families:
| Sample SKU | Kit format | Per-reaction (sample) | Production-scale per-reaction |
| PR2110-S (this product) | Flex Kit (4-tube) | $2.54 | $2.26–$2.27 |
| PR2100-C-S | cDNA Synthesis Kit (2-tube) | $4.05 | $4.40–$5.27 |
The Flex Kit is roughly 50 % cheaper per reaction across the family — likely reflecting the operator-supplied primer-chemistry decision in the Flex Kit (vs Accuris pre-mixing both primers in the Synthesis Kit's buffer).
Procurement Strategy — Both Samples for Direct Comparison
Order both PR2100-C-S and PR2110-S samples ($33 total) for a direct kit-format comparison on the lab's specific RNA template. The decision depends on:
| If the workflow is... | Pick the kit |
| Routine bulk-tissue mRNA cDNA synthesis with pre-mixed primer convenience | PR2100-C qMAX cDNA Synthesis Kit |
| Low-input RNA, primer-chemistry-flexible, method-development | PR2110 qMAX First Strand cDNA Flex Kit |
What 5 Reactions Supports
A typical 5-reaction validation plan:
| Validation step | Reactions used |
| No-template control | 1 |
| Positive control (known RNA template) | 1 |
| Sample RNA cDNA synthesis (oligo dT primer) | 1 |
| Sample RNA cDNA synthesis (random hexamer primer) | 1 |
| Reserve for re-test | 1 |
| Total | 5 |
This supports a Flex Kit-specific validation: confirm both primer chemistries work on the lab's RNA template, validate the high-RTase-concentration low-input workflow if applicable, and confirm downstream PCR / qPCR amplification.
Per Brochure Applications
Per Accuris Life Science Reagents Catalog, applications include cDNA Library Generation, Microarrays, Gene Expression Analysis, 2-Step RT-PCR/RT-qPCR.
Application Profile
Flex Kit first-time evaluation — labs evaluating the Accuris Flex Kit format for the first time use the sample to validate fit before bulk procurement.
cDNA Synthesis Kit vs Flex Kit comparison — labs deciding between PR2100-C and PR2110 formats run both samples for direct comparison.
Low-input RNA workflow validation — labs validating that the high-RTase-concentration Flex Kit handles their specific low-input RNA samples.
Sales / training samples — sales reps and training programs use the sample for hands-on customer demonstrations.
Educational laboratory cDNA exercises — molecular-biology coursework demonstrating primer-chemistry selection concepts.
Ordering & Configuration
Single-use sample SKU. The 5-reaction pack supports a small validation run.
Pair with RNA template + downstream PCR / qPCR reagents. The kit produces cDNA; operator supplies RNA template, primer chemistry selection, and downstream master mix.
Storage. -20 °C, RNase-free handling required.
Confirm at quote: Flex Kit evaluation intent (vs PR2110-50 / -200 production-pack ordering), comparison to PR2100-C kit format, RNA input range needs, and lead time.
Warranty: Per Accuris standard reagent terms — confirm at quote.
