Uncovering Cellular Diversity to Advance Clinical and Translational Research

Single cell sequencing is a next-generation sequencing method enabling in-depth characterization of biomolecules by uncovering genetic expression at single cell resolution. It has advantages over conventional bulk sequencing in its ability to detect rare cell types, uncover tumor heterogeneity, trace lineages, discover drug-resistant cell populations, and characterize complex cell populations such as immune cells in peripheral blood. Q² Solutions utilizes leading technologies such as the 10x Genomics® Chromium™ and Illumina® NovaSeq™ platforms. We can meet your sequencing needs with our extensive services spanning the clinical research continuum combined with our global laboratory network and expert support team.

Sample Preparation & Assessment

We carefully thaw your samples using our automated, temperature-controlled thaws for cryopreserved PBMCs, reducing the risk of operator variability, over thawing, and contamination. We also utilize high-throughput, automated cell counting and laminar flow cell washing protocols to reduce variability and enhance retention and viability.

Library Construction

Each cell is partitioned into nanoliter-scale Gel Beads-in-Emulsion (GEMs) and uniquely barcoded, allowing for labeling and profiling of individual cells. Multiple libraries can be constructed from a single sample, generating multiple readouts that can be linked back to the same single cell.
sequencing

Sequencing

Prepared libraries are sequenced on Illumina® NovaSeq™ to enable high throughput, rapid, and deep sequencing for each cell.

Bioinformatics Analysis and Delivery

Rapid analysis of samples is enabled by robust computational architecture, a mature standard analysis pipeline, and a dedicated team of bioinformaticists. Upon request, an experienced data analytics team is available to consult on your research objectives and enable deep exploration of project data.

Frequently Asked Questions
What is single cell sequencing?
Single cell sequencing is a next generation sequencing method involving single cell isolation, transcriptome characterization, and sequencing library generation. Single cell sequencing uncovers heterogeneity at a high resolution by revealing cellular gene expression, quantity, and diversity in a sample.
What advantages does single cell sequencing have over traditional methods?

The main difference between single cell sequencing and traditional methods of bulk sequencing, qPCR, and flow cytometry is that single cell sequencing allows for characterization of heterogenous samples by profiling the whole transcriptome at a single-cell resolution. Our 96-throughput library preparation capability is a 12-fold increase over traditional methods. Single cell is often used in conjunction with traditional methods to obtain a comprehensive understanding of samples.

What controls do you have in place to limit variability?
We have automated various methods in our workflow to decrease variability. We automate temperature-controlled thaws to replace manual water baths, high-throughput cell counting to obtain objective percent viability and counting, and laminar flow cell washing to reduce manipulation and stress from traditional centrifugation methods. Additionally, we remove dead cells which, if left unaddressed, cause imperfect results and missed sequencing targets.
What data do I receive at the end of the experiment?
