- Accutase® solution is a gentle, non‑mammalian, enzymatic cell‑dissociation reagent widely used for detaching adherent cells and generating single‑cell suspensions without damaging surface proteins. It provides a milder alternative to Trypsin‑EDTA, making it ideal for sensitive cell types such as stem cells, primary cells, neural cells, and cells intended for downstream applications requiring intact membrane markers. Accutase® plays a central role in cell dissociation workflows where high viability, minimal proteolytic damage, and reproducibility are essential.
- Accutase® works through a balanced mixture of proteolytic and collagenolytic enzymes that gently break down extracellular matrix components and cell–cell junctions. Unlike trypsin, which aggressively cleaves peptide bonds, Accutase® maintains a controlled enzymatic profile that preserves cell‑surface antigens, receptors, and adhesion molecules. This makes it particularly suitable for applications such as flow cytometry, immunostaining, stem‑cell passaging, and preparation of cells for transplantation or differentiation assays. Its activity is strong enough to detach cells efficiently but mild enough to maintain structural and functional integrity.
- Accutase® is widely used in workflows involving human pluripotent stem cells (hESCs and iPSCs), mesenchymal stem cells, neural progenitors, endothelial cells, and other fragile cell types. In stem‑cell culture, Accutase® enables gentle passaging that reduces stress and improves post‑dissociation survival. In immunology and flow‑cytometry workflows, it preserves surface markers such as CD antigens, making it ideal for preparing high‑quality single‑cell suspensions. In primary‑cell isolation, Accutase® provides a controlled dissociation environment that maintains viability and reduces mechanical damage. Its reproducibility and low toxicity make it a preferred reagent for laboratories working with sensitive or clinically relevant cell systems.
- Several companies manufacture Accutase® or equivalent gentle dissociation reagents. Innovative Cell Technologies (ICT) is the original developer and supplier of Accutase®, offering sterile, ready‑to‑use formulations suitable for research and industrial workflows. ICT also produces Accumax®, a related reagent designed for tissue dissociation and preparation of highly uniform single‑cell suspensions. Sigma‑Aldrich (Merck) distributes Accutase® under research‑grade packaging, ensuring broad availability and compatibility with standard cell‑culture workflows. STEMCELL Technologies offers Gentle Cell Dissociation Reagent, a non‑enzymatic alternative that provides similar mild dissociation for stem‑cell and organoid systems. Gibco (Thermo Fisher Scientific) provides TrypLE™ Express, a recombinant, animal‑origin‑free enzyme that serves as a gentle alternative to trypsin and is often used alongside Accutase® in sensitive workflows.
- Each reagent incorporates specialised features that enhance performance. ICT’s Accutase® provides consistent enzymatic activity and is free of animal‑derived components, improving regulatory compliance. Sigma‑Aldrich formulations offer high purity and long‑term stability. STEMCELL’s Gentle Cell Dissociation Reagent is ideal for organoids and fragile epithelial systems where enzymatic digestion must be minimised. Gibco TrypLE™ Express provides gentle dissociation with recombinant enzymes, making it suitable for xeno‑free and clinical workflows. These options allow researchers to choose the optimal reagent based on cell type, sensitivity, and downstream applications.
- Proper use of Accutase® is essential for maintaining cell viability and preserving surface markers. The reagent should be pre‑warmed to 37 °C, applied evenly across the culture surface, and monitored under an inverted microscope to avoid over‑digestion. Once cells begin to detach, gentle tapping or pipetting helps complete dissociation. Enzymatic activity should be neutralised promptly using serum‑containing medium or appropriate inhibitors. Over‑exposure can reduce viability, while insufficient dissociation may lead to clumping and inaccurate cell counts. Controlled incubation times and gentle handling ensure optimal results.
- Overall, Accutase® solution is a cornerstone of gentle cell‑dissociation practice. Its ability to detach cells while preserving viability and surface markers supports high‑quality research across stem‑cell biology, immunology, neuroscience, and biotechnology. Whether used for routine passaging, flow‑cytometry preparation, or primary‑cell isolation, Accutase® provides reliable, reproducible, and gentle dissociation suited to the most sensitive cell types.
