Cubipol

The proprietary Cubipol backbone, developed in-house by Cube Biotech, condenses the positive effects of previously available backbones like SMA, DIBMA, and UltrasoluteTM Amphipol. This new development delivers a new multimodal copolymer backbone, making the Cubipol series the first commercially available next-generation copolymer with 9 available off-the-shelf modified variants.

It joins the Next Generation Copolymers AASTY and Ultrasolute™ Amphipol, making solubilization and stabilization of membrane proteins a simpler and more effective endeavor than ever before.

The classic version of the new copolymer backbone shares the hydrophobic capabilities in Ultrasolute™ Amphipol, while boasting lower electric charges, higher backbone flexibility and creating a new opportunity to stabilize previously difficult membrane protein targets.
