Halo Labs, Burlingame, Calif., has launched Aura, an aggregate and particle identification system.
Aura is the next generation of the Horizon, Halo Labs’ backgrounded membrane imaging (BMI) platform. With as little as 5µL and a linear range of over 3×106 particles/mL, BMI can count, size, and image aggregates and particles in the subvisible range (>1 μm). The Aura instrument now adds protein/nonprotein identification using fluorescence membrane microscopy (FMM) and the company says it is the only subvisible particle analyzer on the market to have 100% sample efficiency. An optional second fluorescence channel gives customers the ability to also detect lipids and other drug and process-specific particles.

“Aura is going to completely revolutionize biologic stability analysis,” says Rick Gordon, vice president of sales at Halo Labs. “Finally, there’s an easy way for our customers to identify if large aggregates in their samples are protein or nonprotein without having to resort to slow and cumbersome methods like Raman and FTIR. Particle identification is critical to formulation development and analytical testing in all biologics because it defines the path that needs to be taken to mitigate problems. I’m extremely happy to be able to deliver this solution to our customers.”
