Product Details

Streptavidin microbubbles (Catalog #10025) are shipped as 1 bottle of 800 million Streptavidin Microbubbles.  Store at 4oC.

Key Features

High Buoyancy

With a density of 0.6 g/cm3, Akadeum microbubbles rapidly lift target cells to the top of the sample (typically less than 10 minutes in a microcentrifuge tube, 15 minutes in a 15 mL conical tube).

Excellent Streptavidin Availability

Microbubbles are functionalized with ~ 200,000 streptavidin sites per particle (0.17 nmol sites/mg of bubbles).

Easy Conjugation in Less than 90 Minutes

Beads can be functionalized with biotinylated antibodies or other biomolecules.  Binding efficiency can be confirmed with flow cytometry by staining with a fluorescent secondary antibody.

Separation Permits Positive Selection or Depletion

Once conjugated, microbubbles bind specific cells and are gently and rapidly separated from complex samples.  Microbubbles are compatible with common protein and nucleic acid isolation preps.
