Frequently Asked Questions
1. What can single-cell sequencing be used for?
Applications include tumor heterogeneity, immune cell profiling, developmental biology, stem cell characterization, and tissue regeneration studies. It’s also key in identifying rare cell populations and therapeutic targets.
2. Which single-cell sequencing technologies do you use?
Signios Bio primarily uses 10x Genomics Chromium platforms for single-cell RNA-seq, immune profiling (TCR/BCR), and ATAC-seq. These platforms support high-throughput, high-resolution data generation.
3. What types of samples are accepted for single-cell sequencing?
Signios accepts fresh tissue, dissociated cell suspensions, PBMCs, and cryopreserved single-cell inputs. Each sample must meet cell viability and count thresholds for optimal results.
4. Can you profile immune cells at single-cell resolution?
Yes. Signios Bio offers single-cell TCR/BCR sequencing integrated with gene expression profiling—enabling paired chain analysis and immune phenotype mapping of T-cells and B-cells.
5. What data do I receive from a single-cell project?
Deliverables include raw FASTQ files, Cell Ranger outputs, gene expression matrices, immune clonotype tables, dimensionality reduction plots (e.g., t-SNE, UMAP), and high-quality summary reports.
6. How many cells can be profiled per sample?
Typical experiments capture 5,000–10,000 cells per sample, scalable depending on input quality and project design. Subsampling and enrichment are also possible.
7. Can you help with experimental design and panel selection?
Yes. Signios Bio provides consultative support in sample planning, panel selection (e.g., human vs mouse panels), and protocol optimization to ensure study success.
8. How long does single-cell sequencing take?
Projects generally complete in 3–5 weeks depending on sample quality, complexity, and analysis requirements.
