Description

Welcome the new addition to our NativeMP™ Platform: The Cubipol Series.

The proprietary Cubipol backbone, developed in-house, 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 4 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.
Screening is key to discovering the best copolymer to stabilize your membrane protein target. Try the copolymers individually or save time by screening once and identifying the best stabilizing copolymers for your specific application with our NativeMP™ Screening Kit.

Cubipol Glycerol

This modification of the Cubipol backbone makes it one of the derivates with less charge like Sulfo-Cubipol and Glyco-Cubipol. The low charge makes it, so the copolymer does not interfere with charge-sensitive membrane protein processes like protein-protein and protein-lipid interactions.
Because of its collective features (see Table below), this copolymer can be especially suited for charge sensitive downstream applications.

Lab Results

Hydrpnamic Diameter of Cubipol Nanodiscs
Fig. 1: Hydrodynamic size of Cubipol-DMPC nanodiscs formed with different polymers. Nanodisc size was measured in 150 mM NaCl, 20 mM HEPES at pH 7.5 and a Polymer/DMPC weigth ratio of 3/1.
Wavelenght quantification measurements for Cubipol Nanodiscs
Fig. 2: UV-VIS Extinction measurements of all four Cubipols ranging from wavelength 200-400 nm. The only extinction peak can be measured at around 225nm.
Cubipol Zeta-Potential
Fig. 3: ζ-potential of DMPC nanodiscs formed with different Cubipol copolymers. All four reveal negative net charge. With Glyco-Cubipol being the closest to neutrality at around -15 mV. Meanwhile unmodified Cubipol has the most negative net charge at -25 mV.
