This automation eliminates the tedious manual pipetting steps that characterize traditional approaches while delivering consistent, reproducible results.

Complementing the isoPick system, the isoHub imaging platform provides researchers with an intuitive interface for visualizing and selecting cells of interest. After plating cells into GRID chambers, users can conveniently navigate through the chambers using the isoHub's automated navigation system. The platform captures whole-chamber images without optical edge effects, ensuring clear-cut identification of single cells. Wireless communication between the isoPick and isoHub guarantees a seamless and efficient workflow, eliminating the need for manual coordination between imaging and picking steps.

The platform's flexibility in transferring single cells to different downstream formats represents one of its most valuable features. Researchers can isolate and transfer cells into various volumes and formats, including standard 96-well plates for cell culture, PCR tubes and strips for molecular biology applications, and specialized vials for mass spectrometry workflows. This versatility makes the platform compatible with a wide range of single-cell omics applications, from transcriptomics and genomics to proteomics and lipidomics.

Single-cell omics has emerged as a transformative approach in biological research, enabling comprehensive molecular profiling at the resolution of individual cells. Traditional bulk omics techniques analyze pooled samples of cells, inevitably masking the variability that exists between individual cells. Single-cell approaches, by contrast, enable researchers to dissect this variability across various molecular layers including transcriptomics, genomics, proteomics, and lipidomics, providing unprecedented insights into the complex biological processes that govern cellular function and behavior.

In single-cell transcriptomics, high-throughput sequencing technologies like RNA-seq measure gene expression at the single-cell level, enabling identification of rare cell types, differentiation states, and cellular responses to environmental stimuli. Single-cell genomics focuses on DNA analysis within individual cells, revealing genomic variability, mutations, and copy number alterations that may be completely missed in bulk sequencing approaches. This proves particularly valuable in cancer research, where tumor cells exhibit significant genomic heterogeneity.

Single-cell proteomics involves analyzing proteins using mass spectrometry or antibody-based techniques to study protein abundance, modifications, and interactions in individual cells. This approach reveals how protein networks are reprogrammed in response to different cellular states or diseases. Single-cell lipidomics, an emerging field, examines lipid profiles at the cellular level, offering insights into membrane dynamics, metabolic processes, and signaling pathways, though it faces challenges including the need for highly sensitive techniques and efficient lipid extraction methods.

The iotaSciences platform greatly simplifies the establishment of single-cell omics workflows by automating all tedious liquid handling steps while reliably assuring monoclonality through miniature cell culture chambers. Selected single cells are automatically transferred into various container types compatible with different single-cell omics applications. Samples can optionally be cooled throughout the workflow to preserve precious material and ensure the integrity of various solutes, addressing a critical concern in sensitive applications like lipidomics and proteomics.

The complete single-cell omics workflow begins with creating a single-cell suspension from heterogeneous cell samples through mechanical or enzymatic dissociation. This process typically involves enzymes such as trypsin to break down the extracellular matrix or cell-cell adhesions, followed by gentle pipetting to further separate cells. After dissociation, the suspension is filtered through a mesh or strainer to remove clumps, ensuring a uniform population of single cells ready for isolation.

Following suspension preparation, the automated platform handles the critical isolation step. While traditional manual isolation methods are tedious and unreliable, the scPicking Platform uses miniature culture chambers for easy and reliable monoclonality verification. The system automates all pipetting tasks, from plating single cells to transferring selected cells into vessels compatible with respective applications. This automation eliminates human error and ensures consistent results across experiments.

Different omics applications require different container types for processing. Single-cell genomics and transcriptomics typically use well-plates or tubes, while mass spectrometry-driven approaches require specialized vials. The platform accommodates this diversity by flexibly transferring single cells into various containers including well-plates, PCR plates, tubes, and mass spectrometry-compatible vials, ensuring compatibility with virtually any downstream workflow.

Once single cells have been transferred into assay-compatible containers, samples undergo further processing depending on the specific application. This may involve snap-freezing cells or direct lysis with selected reagents. For single-cell transcriptomics, RNA from lysed cells must be barcoded and reverse-transcribed before NGS library preparation and sequencing. Each application has its own specific requirements, and the platform's flexibility ensures optimal sample preparation for each.

The GRID chamber technology underlying the platform represents a significant innovation in single-cell handling. These ultra-low volume chambers are ideally suited for easily verifying singularity, and once respective chambers have been selected, single cells can be automatically and flexibly transferred into various downstream formats. The chambers eliminate edge effects that plague traditional imaging approaches, providing clear visualization of individual cells and unambiguous confirmation of monoclonality.

Cell viability represents a critical concern in single-cell applications, as downstream analyses require healthy, intact cells to generate meaningful data. The platform addresses this through its ultra-gentle handling protocols and optional temperature control throughout the workflow. The gentle liquid handling minimizes mechanical stress on cells, while temperature control preserves cell integrity and prevents degradation of sensitive biomolecules. These features combine to maintain the highest possible cell viability from isolation through transfer.

The platform delivers consistent and reproducible performance across experiments, a crucial requirement for generating reliable scientific data. Automation eliminates the variability inherent in manual procedures, ensuring that each cell isolation follows identical protocols. This consistency enables researchers to conduct robust comparative studies and confidently interpret differences between samples as biological rather than technical variation.

Documentation and verification capabilities represent another important advantage of the system. The isoHub captures whole-chamber images that provide complete visual documentation of the isolation process. These images serve as permanent records confirming monoclonality and can be archived as part of experimental documentation. This level of verification and documentation far exceeds what is possible with traditional limiting dilution approaches, where visual confirmation of single cells is difficult and unreliable.

The wireless communication between the isoPick and isoHub exemplifies the platform's user-friendly design. This seamless integration eliminates the need for manual coordination between imaging and picking steps, reducing the potential for errors and streamlining the workflow. Researchers can focus on selecting cells of interest rather than managing technical details of the isolation process.

For researchers working with particularly sensitive cell types, the platform's optional temperature control provides essential protection for precious samples. Maintaining appropriate temperatures throughout the workflow prevents degradation of sensitive biomolecules and preserves cell viability, particularly important for applications like lipidomics and proteomics where molecular integrity is critical for accurate results.

The platform's modular design allows it to adapt to different experimental needs and scale from small pilot studies to large-scale screening projects. Whether researchers need to isolate a few dozen cells for detailed characterization or hundreds of cells for comprehensive profiling, the automated system handles the workload efficiently while maintaining consistent quality across all samples.

In summary, the iotaSciences single-cell picking platform represents a comprehensive solution for modern single-cell research.
