Description

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.
