Cube Biotech GmbH

Cube Biotech unleashes the full potential of proteins and supports drug discovery with a powerful CRO service and innovative products. The proprietary NativeMP™ copolymer technology stabilizes membrane proteins in their native lipid environment—ensuring maximum reliability and precision in functional assays and downstream applications. In addition, Cube Biotech offers customized, functionalized magnetic beads as well as high-quality agarose products for the chromatography of proteins and other molecules, including Ni-INDIGO for efficient purification of His-tagged proteins.

Following the merger with IBA Lifesciences in early 2025, Cube Biotech has also added the Strep-tag® product line to its portfolio. The Strep-tag® technology provides a versatile system for the purification and analysis of proteins. It allows for exceptional protein purity (>95%) and analytical applications such as SPR, BLI, high-throughput screenings, and diagnostic tests through highly specific binding properties and picomolar affinity.

Cube Biotech supports scientists at every stage of protein research and offers purification solutions for all protein classes, including challenging membrane proteins. The company continuously develops its innovative product portfolio for the protein and drug discovery market. In the fall of 2025, Cube Biotech launched its PureHTTM Plates: ready-to-use magnetic bead plates for automated protein purification that ensure reproducibility and reduce time consumption.

The manufacturer IBA Lifesciences GmbH, part of the Cube Biotech Group, is certified according to DIN EN ISO 9001:2015.
