General description

HistoDenz™, also known as iohexol, is a non-ionic X-ray contrast compound developed specifically as an iodinated density gradient medium.

Application

HistoDenz™ is suitable for separating everything from macromolecules to viable cells by either rate-zonal or isopycnic centrifugation.
  • It has been used in the isolation and culturing of hepatic stellate cells.
  • It has also been employed in the extraction of microbial cells from environmental samples.
  • It has been used in LacZ (β-galactosidase) staining.
  • It has also been used for the enrichment of gonocytes.

Features and Benefits

HistoDenz™ offers several favorable properties as a gradient medium.
  • It has very low toxicity, low osmolality, high density, and low viscosity (compared to sucrose).
  • It is water-soluble, non-ionic, and chemically near-inert.
