Description

Over 10 years of experience and expertise have culminated in the NativeMP™ copolymer technology featured in this screening kit. Achieve rapid solubilization and stabilization of membrane proteins in a single, detergent-free step.
Membrane proteins are notoriously difficult to stabilize while keeping their structural activity intact. With copolymers, this challenge is tackled by stabilizing the protein together with its native lipid environment. To ensure that you find the best copolymer to suit the unique needs of your membrane protein of interest, we have created a comprehensive selection in this kit. Contact us to learn if it’s suitable for your purposes!

Screening is key

Profit from 30 different copolymers derived from five main backbones: SMA, DIBMA, AASTY, Ultrasolute™ Amphipol and our newest innovation Cubipol. Do a screening to find the optimal copolymer for your membrane protein and save time on optimization processes.

Benefits

  • Convenient Process: Copolymers allow for a single-step solubilization and stabilization directly from the cell.
  • Temperature Stability: Experiments can be carried out at room temperature and up to 37°C.
  • Optimized Stabilization: Preserves the native lipid environment of the membrane protein, retaining its functional stability and avoiding disintegration even of large membrane protein complexes.
  • Faster Process: NativeMP™ Technology is 100% detergent-free. Forget about preparing different buffers and constantly having to add detergents to your solution. With copolymers, you avoid that and save valuable lab time.
  • Application compatibility: Our copolymer technology is compatible with many sensitive downstream applications like phage display, immobilization via SPR, ELISA, and more.

Lab Results

Fig. 1: Side-by-side comparison of the two most prominent stabilization techniques for membrane proteins. Copolymers solubilize and stabilize in a single step and preserve the membrane protein in its native environment. Detergents are added at several points during the stabilization process and stabilize the membrane protein without lipids in a detergent micelle.
Fig. 2: Screening of an ion channel at 4°C and 23°C with NativeMP copolymers.Classic copolymers include SMA and DIBMA. Next generation copolymers include AASTY, Ultrasolute Amphipol and Cubipol. Protein of interest was purified at 4°C/23°C from solubilizate via Rho-MagBeads, eluates were analyzed via SDS-Page and Western Blot. Working at 23°C significantly boosts the elution quantity (up to 200%) compared to 4°C.
