Gamma Biosciences absorbs Nanopareil

Nanopareil, a US-based chromatographic separation technology spinout of South Dakota School of Mines and Technology, has been acquired for an undisclosed sum by Gamma Biosciences, a life sciences equipment-focused subsidiary of investment firm KKR.
Founded in 2011, Nanopareil uses nanofibre membranes for chromatographic separation, the lab technique that isolates distinct chemical compounds from fluids.
The membranes can be adjusted to separate compounds of various different sizes or to account for the way in which they accumulate on the surface.
Nanopareil claims the technique outperforms conventional resin-based separation, offering lower costs and lead-times.
Gamma Biosciences will market the technology through Astrea Bioseparations, a subsidiary focused on biotherapeutic purification tools.
Gamma will also invest in upgrading Nanopareil’s approach, product offering and customer support.
Nanopareil previously closed a round sized at approximately $1m in March 2019 involving state-backed investment unit South Dakota Equity Partners, according to Siouxfalls.Business, which identified Black Hills Angel Fund as a backer but did not say when it had invested.
Craig Arnold, CEO of Nanopareil, said: ” From our first meeting, we quickly developed an extraordinary partnership with Astrea.
“The Astrea team has a strong track record of bringing innovative new products to the market. With their leadership and capabilities, Nanopareil will be well-positioned to become the next-generation market leader.”
