If that's the case I guess we'll see how strong their IP is as the competition builds their own variants of the technology. If the $500 Chromium prep can add real value (biologically or clinically) then 10X have a real chance of becoming a new standard for library prep. Who's going to use Chromium phasing: Is this kind of data going to be relevant enough for people to adopt 10X Chromium as the default genome library prep? I suspect many teams are working on 100s or even 1000s of 10X Genomics genomes right now and we'll see many more publications very soon. Paris japonica 150Gb = 0.02ng = 0.15 genome copies.Salmander 50Gb = 0.07ng = 1.3 genome copies.For the larger non-Human genomes people will need to us a much smaller amount of DNA in a single run, which may limit the number of genome copies to an unreasonable level. For small genomes this gets really interesting and 10X could be an awesome metagenomics tool allowing strain level analysis of complex samples. Many groups will also want to run differently sized genomes and will need to estimate how much DNA to use and how much sequencing they'll require. DNA quality is probably most important and I suspect many people will accept a significant improvement in phasing estimation from lower cost experiments. A single X Ten lane generating 30x coverage looks like it would push scaffold N50 down from 17 to 12 Mb. Tuning 10X phasing to your needs: Users may be able to "tune" scaffold N50 by varying DNA length or sequencing coverage. As such the smaller genome, with DNA fragments of the same size should still have around 60 linked reads per DNA molecule, but a 10MB genome would mean 5% was in each droplet making the phasing much harder to determine. For example, for a genome whose size is 1/10th the size of the human genome (320 Mb), the mean number of LinkedReads per molecule would be about 6, and the distance between LinkedReads would be about 8 kb, making it hard to anchor barcodes to short initial contigs." My first assumption was that genome size would have no impact on linked read depth, but it would significantly affect the amount of the genome present in a single droplet. Analyze full length paired B-cell or T-cell receptors, surface protein expression, antigen specificity, and gene expression, all from a single cell.Ĭhromium Single Cell ATAC (Assay for Transposase Accessible Chromatin) allows you to analyze chromatin accessibility at the single cell level, providing insights into cell types and states, and deeper understanding of gene regulatory mechanisms.Question to the authors: I do not understand the statement about smaller genomes getting lower linked read coverage: "For smaller genomes, assuming that the same DNA mass was loaded and that the library was sequenced to the same readdepth, the number of LinkedReads (read pairs) per molecule would drop proportionally, which would reduce the power of the data type. Explore cellular heterogeneity, identify rare cell types, novel targets, biomarkers, cell types and states.Ĭhromium Single Cell Immune Profiling provides a multiomic solution to your immunology questions. Please contact information about technical procedures, library prep and more and Rita Holdhus at the Genomics Core facility for sequencing.Ĭhromium Single Cell Gene Expression provides single cell transcriptome 3’ gene expression profiles from hundreds to tens of thousands of cells. From assessing tumor heterogeneity and stem cell composition, to dissecting neuronal populations-the technological advancements provided by the Chromium Single Cell Gene Expression Solution, along with turnkey software tools, allow you to maximize insight from any sample type 1.įor more information about the technology, please visit 10X Genomics and the broshure The Power of Single Cell PartitioningĪ checklist of the materials required can be found at the bottom of the page. Go beyond traditional gene expression analysis to characterize cell populations, cell types, cell states, and more on a cell-by-cell basis. Our latest improvements vastly increase sensitivity, so you can detect even more unique transcripts per cell 1. The Chromium Single Cell Gene Expression Solution provides an unparalleled approach to uncover cell-to-cell gene expression variability and identify rare cell types from complex biological samples. Until recently, most molecular studies have relied on bulk analysis, combining all cells into a single average readout. The power of dissecting cell-type differences in complex biological systems is critical to our understanding of cellular contributions during development and in disease progression.
