What is Density Gradient Media?

Density gradient media is a solution used to separate biological particles—like cells, nuclei, and organelles—based on their density. When placed in a density gradient tube and centrifuged, components migrate to the position in the gradient where their density matches the surrounding medium.

AxisShield offers several specialized media with optimal osmolality, pH, and viscosity, ideal for isolating peripheral blood mononuclear cells (PBMCs), lymphocytes, and granulocytes.

Why Choose AxisShield ?

The Axis Shield range of gradient media includes trusted formulations like Lymphoprep™, Polymorphprep™, and Nycodenz®. These products have been cited in thousands of peer-reviewed publications and are widely used in clinical labs and research facilities.

Researchers who search for www axid or www axis often end up at AxisShield-density-gradient-media.com because of:

  • High purity separation
  • Batch-to-batch consistency
  • Easy-to-use density gradient tubes
  • Protocols validated globally

If you're looking for media shield alternatives that deliver consistent outcomes, the AxisShield portfolio is unmatched in reliability.
