Sulfo-SMA Membrane protein solubilization & stabilization
Supplier: CUBE BIOTECH
Sulfo-SMA is an electroneutral modification of existing SMAs. It does not interfere with charge-sensitive interactions between proteins and lipids. This innovation opens up a wider range of experimental research in terms of charge-sensitive membrane protein processes like protein-protein and protein-lipid interactions. In addition, Sulfo-SMA belongs to a new generation of SMA’s which are RAFT polymerized. This achieves a reduction in both monomer size and greater monodispersity.
Another significant advantage of Sulfo polymers compared to other polymers is the wide pH range in which they remain stable. The buffer in which the polymer is supplied has a pH of 7.5, but the polymer itself remains stable between pH 4 and pH 10.
The special physicochemical properties of Sulfo-SMAs make them ideal for cryo-TEM and other downstream applications.
After successful membrane protein solubilization, the protein can be purified using affinity chromatography. For membrane protein purification, we recommend using the Rho1D4-tag. Cube Biotech offers matching products for this purpose.

Sulfo-DIBMA Membrane protein solubilization & stabilization
Supplier: CUBE BIOTECH
Sulfo-DIBMA is an electroneutral modification of existing DIBMAs. It does not interfere with charge-sensitive interactions between proteins and lipids. This innovation opens up a wider range of experimental research in terms of charge-sensitive membrane protein processes like protein-protein and protein-lipid interactions. In addition, Sulfo-DIBMA belongs to a new generation of DIBMA’s which are RAFT polymerized. This achieves a reduction in both monomer size and greater monodispersity. With diisobutylene-maleic acid (DIBMA), you can directly extract membrane proteins from cells without an intermediate step of detergent solubilization, like with SDS, which would usually interfere with the protein's function. Another advantage of DIBMA is the lack of an absorbance maxima at 280 nm. SMAs, in comparison, usually interfere with protein quantification, as aromatic amino acids absorb at the same spectrum.
Another significant advantage of Sulfo polymers compared to other polymers is the wide pH range in which they remain stable. The buffer in which the polymer is supplied has a pH of 7.5, but the polymer itself remains stable between pH 4 and pH 10. The special physicochemical properties of Sulfo-DIBMAs make them ideal for cryo-TEM and other downstream applications.
