Technical excellence

Gold standard QC & Illumina chemistry

Each extraction is matched to your collection method and starting material to maximize yield and integrity. Promega Maxwell instruments and Qiagen kits cover cells, fresh and frozen tissue, and stabilized whole blood, along with dual RNA and DNA extraction from a single sample for multiomic studies.
 
Qubit quantifies and TapeStation qualifies every sample before prep begins, and you receive both reports. If a sample misses threshold, your project manager arranges a replacement, omits it, or moves it to a compatible library prep.

Automated liquid handling removes operator variance, so your samples stay comparable — whether that is eight or eight hundred.

Oligo-dT beads capture mature mRNA by its poly(A) tail, so ribosomal RNA is washed away rather than enzymatically depleted. Fewer steps means less sample lost and over 90% of your reads land on coding transcripts you actually care about — typically 12,000–16,000 expressed genes detected per sample, depending on depth and tissue.
dUTP second-strand marking holds strand specificity above 98%, where non-stranded kits lose transcript origin entirely. Overlapping genes are quantified separately, antisense transcription is detectable, and dense regions resolve to the correct gene.

Illumina NovaSeq X Plus with 2x150 bp paired-end chemistry and Unique Dual Indexes to prevent index hopping. Read depth is configurable from 10M to 40M+ paired reads per sample based on your analysis goal.

Frequently asked questions

Planning your mRNA-Seq project

Samples & service

Because our standard RNA-Seq uses poly(A) capture, degraded RNA lacks the intact poly(A) tails needed for binding. This leads to severe 3′ bias or library preparation failure. For low RIN scores or FFPE tissue, we recommend switching to our Total RNA-Seq with ribosomal depletion or low-input RNA-Seq workflows, which do not rely on poly(A) integrity.

No. Bacterial mRNA does not possess stable poly(A) tails. For prokaryotic systems, use our ribosomal depletion workflow, which selectively removes bacterial rRNAs while preserving all underlying transcripts.

Yes. For species with an available reference we align to the standard annotation. Without a reference we can run a de novo transcriptome assembly and quantify against it, or align to the closest annotated relative. Discuss your organism with us during study design so we can set expectations on annotation depth.

Yes. If you cannot isolate the RNA yourself, ship us pelleted cultured cells, flash-frozen tissue blocks, or whole blood in stabilizing tubes. Our team performs automated magnetic-bead extractions for an additional per-sample fee.

Data & delivery

FASTQ files and a QC report via secure FTP, S3, or BaseSpace.

20–30 M reads/sample
Cost-effective profiling, accurate quantification of medium-to-high abundance transcripts, and standard differential expression.
50 M+ reads/sample
Alternative splicing analysis, low-abundance transcript detection, and gene fusion mapping.
100 M+ reads/sample
Novel isoform discovery and comprehensive allele-specific expression analysis.

Your data is available on our secure FTP for 2 weeks after delivery, and we retain it in storage for 60 days. Extension options are available — ask your project manager, or request a direct transfer to your own AWS, Globus, or cloud storage.

Yes. Analysis can be added any time. If within the 60-day data retention window you will not need to resubmit the data. Contact your project manager and we will quote the additional analysis.

Ordering & logistics

Register your samples in the customer portal to generate your shipping documents, then print them and include them in your package. All samples should be shipped on dry ice overnight, or you can schedule a local same-day courier in the SF Bay Area.

Submit your inquiry below and our team will help create an account and walk you through submitting your samples.

Standard turnaround is 3 to 4 weeks from the day your samples pass incoming QC to final data delivery. Expedited processing is available on every order, in 10 to 14 business days — just ask your project manager.

There is no order minimum. We do recommend at least three biological replicates per condition for reliable differential expression, and per-sample pricing improves with batch size.
