Frequently Asked Questions
Everything you need to plan your project
How do I choose the right service?
- Bulk (Takara/Cellecta): Best for cost-effective, deep tracking of clone frequencies and aggregate diversity.
- Single-Cell (10x Genomics): Best for linking exact paired chains (αβ or heavy-light) to individual cell phenotypes.
- Spatial: Best for mapping immune architecture directly within tissue sections.
What species are supported?
We specialize in Human, Mouse, Rat, and NHP.
- Takara: Supports Human, Mouse, Rat, and NHP.
- 10x Genomics: Supports Human, Mouse, and Rat.
- Cellecta: Primarily engineered for Human and Mouse.
Which bulk kit should I choose?
- Takara SMARTer: Best for full-length V(D)J sequencing of variable regions.
- Cellecta Full-Length: Complete V(D)J variable region sequencing.
- Cellecta CDR3: Best for absolute digital clonotype quantification and rare subset analysis.
What are the input requirements?
- Purified RNA: 20 ng – 1,000 ng total RNA (RIN >6 preferred). Working volume 15 µl
- Cell Suspensions (Bulk): 50,000 cells recommended; 100 cells minimum.
- Single-Cell: 1 – 1,000,000 cells (>85% viability).
- FFPE Tissues: 5–8 slides/core curls (10 µm thickness) with DV200 > 20%.
What is your turnaround time?
- Standard: 3–4 weeks from QC approval.
- Expedited (Bulk only): 10–12 business days.
Where is sequencing performed and on what platforms?
All work is done in-house at our Foster City, CA facility using Illumina NovaSeq X Plus and MiSeq i100 platforms.
What quality control (QC) do you provide?
We perform rigorous Qubit and TapeStation validation on all incoming samples and provide formal reports for your sign-off before library construction begins.
