General description

OptiPrep™ Density Gradient Medium, also known as iodixanol, is a low osmolarity, non-ionic iodinated density gradient medium. It is a sterile and endotoxin-tested solution that comprises 60% (w/v) iodixanol in water, designed for the in vitro isolation of biological particles. It may be used for fractionation and separation of cell and subcellular organelles.[1]

Application

OptiPrep™ has been used to isolate molecules, cells, and subcellular organelles, including DNA, cytokines, lysosomes, endoplasmic reticulum, peroxisomes, T lymphocytes, and natural killer cells.[1] It has also been used for the following applications:

  • to investigate the efficiency of single-cell encapsulation.[1]
  • the gradient-based isolation of senescent cancer cells.[2]
  • isolation of non-enveloped virion isolation from bronchoalveolar lavage.[3]
  • isolation of lipoproteins and macromolecules
  • purification of virions
  • purification of neuron cells

Features and Benefits

OptiPrep™ has numerous biocompatible properties that make it ideal for use.
  • It is biologically inert and does not interfere with assays for marker enzymes.[1]
  • It is non-ionic, non-toxic, and has low osmotic pressure.
  • It forms spontaneous gradients that are stabler and easier to prepare than sucrose.[2]

Other Notes

60% (w/v) solution of iodixanol in water (sterile).
