KROMATID'S Next-Gen Cytogenetics

Here at Kromatid, we believe that visually confirming karyotype across as many cells as possible is essential.
Because when a single cell can pose risk, numbers matter.

Why does conventional cytogenetics miss the mark? It’s really all in the number of cells analyzed. FDA guidance states that visually confirming chromosome integrity with G-Banding analysis or other sensitive methods should be used. And that at very minimum, at least 20 cells should be analyzed to understand mutagenesis risk.

Why only 20 cells? Because conventional karyotyping methods, while they are the gold standard for visualizing chromosomes, are typically run on 20-50 cells. Preparation, imaging and analysis are highly manual and specialized, and analysis for mutation requires highly qualified human expertise examining each chromosome for structural abnormalities.

  • Analysis of 20-50 cells will detect chromosome abnormalities present in about 1 out of every 10 cells, or at 10% prevalence. Low-prevalence mutations, will be missed.
  • Our mission at KROMATID is to bring the power of these single cell measurements into the hundreds and thousands of cells, which we profile routinely – enabling mutations with 0.1% prevalence can be detected with confidence.

Many different types including whole blood, PBMCs, IPS, T-cells, NK, γ δ T-cells, hepatocytes, hepatoblasts, HEK, and HEP variants.
What are structural variants and why are they important?

Structural variants (SVs) are large-scale changes in chromosome structure, including deletions, duplications, inversions, translocations, and insertions. These genomic alterations can occur naturally or arise during cell engineering, gene editing, viral vector integration, or cell manufacturing.

Understanding structural variants is critical because they can affect gene function, genomic stability, cell performance, and, in some cases, patient safety. Detecting these events early in development helps researchers evaluate genomic integrity, optimize manufacturing processes, assess potential risks, and support regulatory submissions.

KROMATID's KROMASURE™ platform enables direct, single-cell visualization of structural variants at the chromosome level, allowing researchers to identify rare or complex events that may be difficult to detect using population-based genomic methods alone.

Who can benefit from KROMATID's technology?

KROMATID's technology is designed for organizations developing and manufacturing advanced cell and gene therapies that require a deeper understanding of genomic integrity. Our services support biotechnology and pharmaceutical companies, academic and translational research institutions, contract development and manufacturing organizations (CDMOs), and clinical research organizations (CROs).

The KROMASURE™ platform is valuable across the development lifecycle—from early research and process development through IND-enabling studies, manufacturing, and post-market applications. It is particularly beneficial for teams working with gene editing technologies, viral and non-viral delivery systems, stem cells, immune cell therapies, induced pluripotent stem cells (iPSCs), and other genetically modified cell products where chromosome-level genomic integrity is a critical quality attribute.

How is KROMATID different from other genomic analysis companies?

KROMATID provides a unique view of genomic integrity by directly visualizing chromosomes at the single-cell level. While many genomic technologies generate population-averaged data or infer structural changes through sequencing, KROMATID's proprietary KROMASURE™ platform enables researchers to observe chromosome-scale structural variants within individual cells.

This approach can reveal rare, complex, or heterogeneous genomic events that may be difficult to detect with traditional methods alone. By providing chromosome-level insight, KROMASURE™ complements sequencing and other genomic assays, helping developers gain a more complete understanding of genomic integrity throughout cell and gene therapy development.

Combined with our scientific expertise, flexible study design, and support for RUO, GLP, and GMP testing, KROMATID delivers actionable data that helps customers make informed development, manufacturing, and regulatory decisions with greater confidence.

What is directional Genomic Hybridization (dGH)?

Directional Genomic Hybridization (dGH®) is KROMATID's proprietary chromosome imaging technology that enables the direct visualization of structural genomic changes at the single-cell level. Unlike methods that infer genomic alterations from sequencing or population-averaged data, dGH® allows researchers to examine individual chromosomes and identify structural variants such as inversions, translocations, insertions, deletions, and other chromosome rearrangements.

This unique approach provides high-resolution, chromosome-level insight into genomic integrity, making it especially valuable for evaluating gene editing outcomes, vector integration, cell manufacturing processes, and other applications where rare or complex structural variants may be important.

dGH® serves as the foundation of some of KROMATID's KROMASURE™ platform, enabling researchers and developers to generate actionable genomic integrity data that complements sequencing and other orthogonal analytical methods.

What is Pinpoint FISH and how does it work?

PinPoint FISH is KROMATID's proprietary fluorescence in situ hybridization (FISH) technology designed to precisely detect and localize specific DNA sequences within individual cells. Using custom fluorescent probes that bind to targeted genomic regions, PinPoint FISH enables researchers to directly visualize the location, copy number, and chromosomal context of genes, transgenes, or vector integration sites.

Unlike chromosome-based analyses that require metaphase cells, PinPoint FISH can be performed on interphase cells, allowing the analysis of a much larger number of cells and enabling the detection of rare events with greater statistical confidence. This makes it particularly valuable for assessing heterogeneous cell populations and applications where high-throughput analysis is important.

PinPoint FISH is commonly used to confirm genome editing outcomes, characterize vector integration, assess insertional copy number, and evaluate genomic integrity during cell and gene therapy development. It can be used as a standalone assay or in combination with KROMATID's KROMASURE™ platform to provide a more comprehensive understanding of genomic integrity.

 What are the differences between SCREEN and KBAND (G-Banding)?
Screen is based on hybridization of fluorescent probes designed against the specific sequence of the human genome while G-banding is a staining technique based on Giemsa staining of heterochromatin (dark) and euchromatin (light). The lower limit of event resolution for Screen is ~20 kb while the lower limit of event resolution for G-banding is ~ 5Mb.
Can KROMATID work with clinical samples (e.g., FFPE, blood, cultured cells)?

No. KROMATID does not work with clinical sample types such as FFPE tissue, peripheral blood, or primary uncultured clinical specimens.

Our assays are designed for research and development applications using well-characterized cell populations, including cultured cells and cell line–based systems used in cell and gene therapy development. This ensures optimal performance of our single-cell, chromosome-level imaging technologies and the reproducibility required for high-resolution genomic integrity analysis.

If you are unsure whether a specific sample type is compatible, our team can help assess suitability during the study design process.

Do you perform cytogenetic testing services on plant and animal cells?
We do not provide services for plant cells. We can design and run custom projects for different animal species. We have carried out projects for customers using various species including canine, murine, bovine, CHO, and NHP cells.  
How is your KBAND different than G-Banding?
  •  K-banding is a fit-for-purpose assay with analysis and data presentation designed to look at many cells from heterogeneous cell populations and highlight low-prevalence events in a format that provides a comparison of a treated sample to a matched donor. G-banding classically utilized in a clinical format to look at a few cells in a patient sample for an event or events that should be present at a high prevalence.
Can I buy a probe and do this myself?

No. KROMATID does not offer its probes or assays for standalone purchase or self-directed use.

Our technologies require specialized expertise not only in assay execution, but also in the interpretation of complex, high-resolution chromosome-level imaging data. Meaningful analysis depends on deep experience in identifying and classifying structural variants, as well as understanding the biological and manufacturing context in which they occur.

For this reason, KROMATID provides its solutions as a fully supported service, where our scientific team performs the assay, conducts rigorous analysis, and delivers interpreted results. This ensures consistency, accuracy, and actionable insights that have not been reliably achieved when attempting in-house implementation.

Why should we test starting material?

Starting material analysis is critical because the genomic quality of your input cells directly influences the safety, consistency, and performance of the final cell or gene therapy product.

Even in carefully controlled systems, starting cell populations can contain rare structural variants, pre-existing genomic instability, or donor-to-donor variability that may not be detected using bulk or population-averaged methods. These hidden differences can be amplified during manufacturing and expansion, potentially impacting product quality and downstream clinical outcomes.

By evaluating starting material at the single-cell, chromosome level, KROMATID helps identify these rare or heterogeneous genomic events early in development. This enables better donor selection, improved process design, and a more informed baseline for monitoring genomic changes throughout the manufacturing workflow.
