- Follow Protocols – Incubation times and temperatures are optimized for results
In cell culture workflows, separating adherent cells from their substrate or breaking down complex tissues into single-cell suspensions is a crucial step. Whether you are passaging cells, preparing them for downstream analysis, or isolating primary cells from tissue samples, your choice of dissociation reagent directly affects viability, yield, and reproducibility.
STEMCELL Technologies offers a precisely engineered tissue and cell culture dissociation reagent that can preserve cell functionality while ensuring efficient detachment or tissue breakdown. These solutions meet the needs of researchers in stem cell biology, immunology, oncology, and regenerative medicine.
This article highlights select reagents available in South Africa. However, the full STEMCELL Technologies range is accessible on request.
Why Dissociation Reagents Matter in Cell Culture
Dissociation is more than a physical separation. It is a precisely balanced chemical and enzymatic process that must protect cell integrity. The right reagent allows researchers to:
- Preserve Cell Surface Markers – Essential for flow cytometry, immunostaining, and cell sorting.
- Maintain Viability – Gentle formulations reduce stress and apoptosis.
- Ensure Consistency – Uniform dissociation improves reproducibility across experiments.
- Support Diverse Applications – From routine passaging to complex tissue digestion.
When dissociation methods are too harsh, they can damage cell membranes, remove essential surface proteins, and compromise downstream results.

Featured Product: Gentle Cell Dissociation Reagent
The Gentle Cell Dissociation Reagent uses a non-enzymatic formulation to detach adherent cells while preserving structural and functional integrity. It is highly suitable for applications requiring high viability and intact surface markers.
Key Features
- Minimizes proteolytic damage.
- Maintains viability for sensitive stem and primary cells.
- Works for routine passaging and harvesting.
- Compatible with downstream immunological assays and molecular analyses.
Common Applications
- Passaging Pluripotent Stem Cells (PSCs) – Retains colony morphology and pluripotency.
- Harvesting Primary Cells – Protects fragile epithelial and endothelial cells.
- Preparing for Flow Cytometry – Preserves surface proteins for accurate staining.
Selecting the Right Dissociation Reagent
When deciding which reagent to use, consider:
- Cell Type – Some cells tolerate enzymes, while others require gentler methods.
- Downstream Application – Studies involving receptor binding or marker analysis demand epitope preservation.
- Culture Conditions – Coating materials, media composition, and substrate stiffness influence performance.
- Time Requirements – Fast detachment benefits high-throughput work, while slower processes protect delicate cells.
Integration into STEMCELL Technologies Workflows
These dissociation reagents integrate seamlessly with STEMCELL Technologies cell culture media, supplements, and cultureware, ensuring consistent and reproducible conditions.
For example:
- Pair the Gentle Cell Dissociation Reagent with mTeSR™1 medium for optimal PSC growth and handling.
