USphere Labeler FLA (LA with FITC)

The Usphere Labeler FLA agents have been functionalized with a biotin-avidin molecule to allow researchers to conjugate targeting moieties or antibodies to the microbubble; additionally, this agent contains the FITC fluorescent dye. These agents are 1.1-1.4µm in size, with a concentration of >2.5x1010 microbubbles/ml; each vial contains 0.8ml.

These agents are shipped at room temperature but may be stored at 2-8oC for up to 6 months.

Once activated, using the UltraMix Agitator (a one-time purchase) the microbubbles can be used for up to 3 days with >90% performance when properly stored.
