The SMALP products have been developed for biomedical purposes, in particular, for the solubilization of (biological) lipid membranes and isolation & purification of integral membrane proteins.
After solving the SMA + buffer powder in water, the product is ready-to-use. It can primarily used for all cell membrane hosts, including bacteria, yeast, and human cells. After successful solubilization of the membrane protein, 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-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.
Good publications to find details about Sulfo-SMA and Sulfo-DIBMA are:

The Ultrasolute family evolved from the first amphipol A8-35 is used for highly efficient solubilization and stabilization of membrane proteins without the use of detergents while preserving their activity. They demonstrate tolerance to moderate concentrations of divalent cations and exhibit no absorption at wavelengths >250 nm.

Each membrane protein has its native lipid environment. Therefore, each lipid environment is unique to each membrane protein. Moreover, it is this lipid environment that synthetic polymers like AASTYs interact with. Therefore, one needs a broader selection of polymers since there is not one AASTY that fits each phospholipid composition. To address this question, AASTYs come in three different ratios of acrylic acid to styrene. The ratios differ in hydrophilic property of AASTY, which results in different affinities to varying membrane lipid compositions. The second feature to screen for when it comes to AASTY is the size of the resulting nanodiscs. One of AASTY's most excellent features, compared to SMA or DIBMA, is that its nanodiscs are pretty uniform in size. Therefore, the correct fitting nanodisc size must be determined before.

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 as a tool for protein solubilization is the lack of an absorbance maxima at 280 nm. In comparison to SMAs, this would usually interfere with protein quantification, as aromatic amino acids absorb at the same spectrum. PureCube DIBMA is lyophilized from two different buffer solutions (HEPES or TRIS) to ensure a stable pH of 7.5, which is ideal for most protein solubilizations. A good publication to read even more details about DIBMA is Oluwole et al. 2017.

The SMALP BZ series was developed in collaboration with Prof. Bert Klumperman from Nanosene, a spinout company of Stellenbosch University in South Africa. The goal was to create SMALPs that are synthesized via RAFT polymerization, achieving a better defined polymer size and a low dispersity (narrow chain length distribution). This is a significant improvement over previous SMALPs. The SMALP BZs are thus more efficient in dissolving the cell membranes and increasing protein yield.
After successful solubilization of the membrane protein, 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.
