Shared seq budget fit
SHARE-seq measures chromatin accessibility and gene expression from the same single cell, demanding high-quality libraries and precise reagent handling. Skimping on core consumables often leads to high dropout rates, forcing you to sequence deeper and ultimately spending more. When evaluating options, prioritize kits that offer integrated workflows for scATAC and scRNA to reduce hands-on time and minimize technical variance.
Consider the total cost of ownership, not just the sticker price. This includes sequencing depth required to get usable data, labor costs for library prep, and the potential need for repeat experiments if the initial run fails. A slightly more expensive kit with higher efficiency can save money by reducing the number of cells you need to load and the sequencing reads required for analysis.
We've selected several options that balance performance with cost-effectiveness for different research scales. These tools are designed to streamline the SHARE-seq workflow, making it more accessible for labs with varying budgets and technical expertise.
Shortlist real options
SHARE-seq (Single-cell Chromatin Accessibility and mRNA Expression) is an extensible platform designed to measure scATAC and scRNA from the same cell. This approach links distal regulatory elements to key gene expression changes, offering a comprehensive view of regulatory circuitry across diverse cells in tissues. While the technique itself is a scientific methodology rather than a consumer product, researchers often look for the specialized tools and reagents required to implement this workflow.
The following options represent the core components typically associated with SHARE-seq workflows. These items are selected based on their role in enabling single-cell multiomics profiling. Note that specific kit availability and pricing should be verified with suppliers, as genomic reagent catalogs change frequently.

When evaluating these tools, prioritize compatibility with your existing sequencing platform. The success of SHARE-seq depends heavily on the efficiency of the tagmentation and cDNA synthesis steps. Ensure that the reagents you choose are validated for single-cell applications to avoid data loss or increased noise. For detailed protocol guidance, refer to the original SHARE-seq publications or the seqWell platform documentation.
Inspect the expensive parts
SHARE-seq is a powerful platform, but it is also fragile. The reagents are costly, and the workflow requires precise timing. A single error in library preparation or sequencing setup can waste thousands of dollars in materials and weeks of bench time.
Before you commit to a full run, use this checklist to inspect the components most likely to cause failure. Focus on these high-risk areas to protect your investment and ensure data integrity.
Verify that your combined ATAC and RNA libraries have sufficient complexity. Low complexity leads to poor cell recovery and biased gene expression data. Use a Bioanalyzer or TapeStation to confirm fragment size distribution and concentration before pooling.
Poor cell viability directly impacts doublet rates and data quality. Ensure your single-cell suspension is free of debris and clumps. Aim for a viability rate above 85% before loading onto your droplet-based or microwell platform to maximize the number of usable cells.
SHARE-seq requires balanced sequencing depth for both ATAC and RNA reads. Insufficient depth for ATAC leads to poor peak calling, while low RNA depth misses rare transcripts. Check your sequencing provider’s specs to ensure a 1:1 or optimized ratio for your specific cell type.
Many failures stem from degraded enzymes or buffers. Check the expiration dates of Tn5 transposase, reverse transcriptase, and ligation mixes. Store reagents at the recommended temperature and avoid repeated freeze-thaw cycles, which can significantly reduce enzymatic activity.
Ensure your analysis pipeline supports the dual-modality output of SHARE-seq. Standard RNA-seq or ATAC-seq pipelines may not correctly handle the combined BAM files. Verify that your tools can jointly quantify chromatin accessibility and gene expression from the same cell.
By systematically checking these five areas, you can minimize the risk of costly failures. This proactive approach ensures that your SHARE-seq experiment yields high-quality, publishable data without unnecessary re-runs.
Ownership costs and maintenance surprises
A low sticker price for a SHARE-seq kit rarely reflects the true cost of running the assay. The workflow requires precise coordination between chromatin accessibility and mRNA library preparation, which means you are effectively running two complex protocols in parallel. If one step fails, the entire sample is lost, and you must start over from tissue dissociation.
Hidden expenses in the workflow
The initial reagent cost is only the beginning. You must factor in the cost of high-quality single-cell isolation devices, specialized barcoding reagents, and the bioinformatics compute power needed to integrate scATAC and scRNA data. Many labs underestimate the time required for library QC, which often demands additional purification steps to remove adapter dimers and ensure balanced representation of both modalities.
When "cheap" stops being cheap
Budget kits may lack the robustness needed for difficult tissue types, leading to higher dropout rates. A failed run costs more than the reagents alone; it consumes valuable researcher time and delays downstream analysis. Investing in a platform with consistent performance and clear workflow documentation often reduces the total cost of ownership by minimizing repeat experiments and data reprocessing efforts.
