About OptiPrep™
OptiPrep™ is a high-purity density gradient medium based on iodixanol, widely used for the separation and purification of biological particles using density gradient centrifugation. This ready-to-use OptiPrep density gradient solution enables efficient isolation of cells, viruses, organelles, and extracellular vesicles while maintaining physiological osmotic conditions.
The OptiPrep iodixanol density gradient medium provides excellent resolution and reproducibility during ultracentrifugation. Unlike traditional gradient materials, iodixanol solutions remain iso-osmotic across a wide range of densities, helping preserve biological activity and cellular integrity during separation procedures.
OptiPrep density gradients are commonly used in research laboratories for virus purification, exosome isolation, membrane fractionation, and organelle separation. The medium allows researchers to create either continuous or discontinuous density gradients, offering flexibility for many experimental protocols.
Manufactured under strict quality standards, OptiPrep™ ensures high purity, low endotoxin levels, and consistent performance for demanding biological applications. The solution is sterile filtered and designed for reliable use in density gradient centrifugation workflows.
Key Features
- High-purity OptiPrep iodixanol density gradient medium
- Iso-osmotic solutions across a broad density range
- Ideal for ultracentrifugation and density gradient separations
- Excellent resolution for virus, vesicle, and organelle purification
- Sterile filtered and produced under controlled conditions
Typical Applications of OptiPrep Density Gradients
The OptiPrep density gradient medium is widely used in many biological and biomedical applications, including:
- Virus purification and viral particle isolation
- Exosome and extracellular vesicle purification
- Organelle separation (mitochondria, nuclei, lysosomes)
- Cell fractionation and membrane isolation
- Lipoprotein and protein complex separation
Thanks to its iodixanol formulation, OptiPrep density gradients provide improved viability and structural preservation compared to traditional sucrose or cesium chloride gradients.
Why Use OptiPrep Iodixanol Gradients?
OptiPrep iodixanol solutions offer several advantages over conventional density gradient media. Because iodixanol forms iso-osmotic gradients, biological samples experience minimal osmotic stress during centrifugation. This property is particularly important when isolating delicate structures such as viruses, extracellular vesicles, or subcellular organelles.
The OptiPrep density gradient medium also allows precise control over density ranges, enabling researchers to optimize separation conditions for their specific samples.
