You Searched For: Sulfo-DIBMA

Supplier: CUBE BIOTECH

Description: 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.

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.

Description: Glyco-DIBMA is a modified version of DIBMA with a sugar side-chain added to the polymer molecule. Its purpose is to enhance DIBMA's range for solubilizing membrane proteins. After solving the Glyco-DIBMA + buffer powder in water, the product is ready-to-use. It can primarily be used for all cell membrane hosts, including bacteria, yeast, and human cells. After successful solubilization of the membrane protein of interest, the protein can be purified using affinity chromatography. We recommend the Rho1D4-tag for membrane protein purification and offer matching products for this purpose. DIBMA / Nanodisc Screening: Each membrane protein may perform better or differently with certain synthetic polymers. This is due to the characteristic composition of phospholipids surrounding the membrane proteins. Therefore a screening process for the correct DIBMA/Polymer is required in before. For this purpose, we offer our synthetic nanodisc screening kit MAXI which contains DIBMA, AASTY, and SMA.

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.

Description: Membrane proteins and their composition are as versatile as the whole cell membrane itself. For this reason, it is impossible to predict with 100% accuracy which SMALP product is best suited for the solubilization and subsequent preparation of your membrane protein of interest. We offer this SMALP Screening Kit that consists of our four individual SMAs. This way, you can conveniently screen for the best SMA for your protein before scaling up your assay. In case you would like to extend your polymer screening beyond the reaches of SMA, we offer our Synthetic Nanodisc Screening Kit, which covers both SMA and DIBMA.
