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.

Custom Cell Isolation Made Possible

Akadeum’s Streptavidin Microbubbles product allows the researcher to use their own biotinylated antibodies. Once conjugated, microbubbles gently and rapidly separate target cells from complex samples.
