Breaking the Single Cell Bottleneck: How ScalePlex is Revolutionizing Single Cell RNA-seq

As researchers hunger to explore more cellular landscapes, the traditional scRNA-seq workflow becomes a financial and logistical labyrinth. More samples mean exponentially rising costs, more complex protocols, and diminishing returns. It's like wanting to understand an entire ecosystem but being constrained to studying just a few square meters. Enter a groundbreaking multiplexing kit that shatters these limitations. This technological breakthrough doesn't just incrementally improve research – it reimagines what's possible. By scaling sample throughput from dozens to potentially thousands of samples, researchers can now map cellular diversity with unprecedented breadth and depth.

How ScalePlex Works

ScalePlex is a fixation enabled method of multiplexing that utilizes numerous sets of 96 tags to massively scale up sample throughput with a convenient, streamlined workflow. By leveraging a large sample pooling strategy combined with the standard 96 sample input to ScaleBio’s scRNA-seq workflows, the platform enables massive multiplexing up to 9,216 samples (96 ScalePlex tags x 96 RT barcodes) with a significant reduction in tedious and time-consuming workflow steps.

ScalePlex tags are proprietary modified oligos, designed to be compatible with single cell RNA sequencing on Scale Bio platforms. Tags attach to the cell or nucleus during fixation, and leverages the same massively parallelized barcoding technology to barcode the tags alongside the RNA library.

From Dozens to Thousands: Unleashing True High-Throughput Analysis  

Other high throughput methods impose physical limitations on throughput by processing individual samples in a single 96 well plate, or only allow for small sample pools of up to 16 tags. The ability to combine 96 samples into a single representative sample pool increases the number of samples that can be multiplexed with a significantly more streamlined workflow.

This comparison demonstrates the workflow strain that is removed when handling 96 samples at a time rather than pools of 16. Pooling more samples reduces washing and counting steps, saving time and enhancing cell recovery.

One Solution, Endless Possibilities  

Compared to antibodies and probes, ScalePlex is species-agnostic and can be used broadly across experiments without the need for optimization or titration. ScalePlex oligos can be used as you need them, when you need them. Whether the experiment requires hundreds of banked samples or isolating a few nuclei samples per day, the oligos can be thawed and frozen to use at any pace, with a fixation-enabled workflow to lock in biology.

Built for Discovery: Where Power Meets Precision 

ScalePlex is compatible with all ScaleBio 3’ RNA sequencing platforms including the current scRNA v1.1 kit as well as the next generation QuantumScale platform, ensuring high sensitivity and ideal for discovery of novel transcripts, without sacrificing on multiplexing potential and streamlined library preparation. This technology is compatible with genetic demultiplexing methods, providing additional advantage for deeper discovery over other probe-based methods.

Accelerating Tomorrow's Breakthroughs, Today 

ScalePlex fixation is compatible with both the Single Cell RNA Sequencing Kit v1.1 and QuantumScale RNA Sequencing, ensuring seamless integration into existing research workflows. This thoughtful design means laboratories can immediately leverage the technology without extensive retooling or retraining.

ScalePlex technology represents more than just an incremental advancement. As researchers generate more sophisticated, large-scale cellular atlases, we move closer to truly personalized approaches in medicine, drug discovery, and our fundamental understanding of biological complexity. The future of biological research is not just about generating more data—it's about generating more meaningful, transformative insights.
