A low-viscosity, non-toxic medium suitable for density gradient centrifugation of cells, viruses and subcellular particles.

  • Composed of colloidal silica coated with polyvinylpyrrolidone (PVP), which gives low osmolality and low viscosity.
  • For separation of cells, subcellular particles and larger viruses (down to ~ 70S) under gentle conditions which preserve viability and morphological integrity.
  • Non-toxic to cells.
  • Adjustable to physiological ionic strength and pH.
  • Gradients can either be pre-formed or spontaneously generated by centrifugation at moderate speeds in an angle-head rotor.
  • Gradients are iso-osmotic throughout and cover a range of densities up to 1.3 g / mL.

Quick and easy

Percoll is a low viscosity density gradient medium for preparation of cells, subcellular particles, and larger viruses. The low viscosity of the medium enables cell preparation on preformed gradients in only a few minutes using low centrifugal forces (200 to 1000 × g). The medium is available in easy-to-open, resealable 250 mL and 1 L bottles.
