PercollR Cytiva 17-0891-02

Percoll(R) is composed of colloidal silica coated with polyvinylpyrrolidone (PVP). It 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 x g). This medium is non-toxic, almost chemically inert, does not adhere to membranes and can be stored unopened at room temperature for five years.
