GE Healthcare's Percoll and Percoll Plus by Cytiva

GE Healthcare's Percoll.

Percoll is a silica-based colloidal medium for cell separation by density gradient centrifugation. The silica particles of the medium are coated with polyvinylpyrrolidone (PVP), which gives low osmolality and low viscosity.

GE Healthcare's Percoll offers:

• Low osmolality: Percoll can easily be adjusted with physiological saline, cell culture medium, or sucrose to give gradients that are iso-osmotic throughout.
• Low viscosity resulting in rapid formation of gradients and particle separation at low centrifugal forces.
• Support through extensive research use: thousands of publications on Percoll in scientific journals.
• Formation of either continuous preformed or self generated gradients by centrifugation at
  moderate speeds.

GE Healthcare's Percoll PLUS

Percoll PLUS is a silica-based colloidal medium for cell separation by density gradient centrifugation. The silica particles of the medium are covalently coated with silane, providing product stability and long shelf life.

GE Healthcare's Percoll PLUS offers:

• Low endotoxin levels (max. 2 EU/ml).
• Absence of toxicity for cells and very low chemical reactivity.
• Low osmolality: Percoll PLUS can easily be adjusted with physiological saline, other balanced salt solutions, or cell culture media, to give gradients that are iso-osmotic throughout.
• Low viscosity resulting in rapid formation of gradients and particle separation at low centrifugal forces.
