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.

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.

AASTYs (Acrylic acid-co-styrenes) - like AASTY 6-55 - are highly-alternating copolymers, well-suited for generating native lipid nanodiscs. They are a 2022 novel developed series for membrane protein solubilization & stabilization. AASTY 6-55 gets its name from its molecular weight and Acrylic Acid : Styrene Ratio. These varying ratios of acrylic acid to styrene contribute to the hydrophilic properties of our AASTYs. In general, lighter AASTYs, like 6-55 tend to be more aggressive, while heavier AASTYs, such as 11-45 show higher thermodynamic stability.

The exact composition of AASTY copolymers shows different extraction efficiency, depending on the lipid composition of the lipid bilayers being formulated into nanodiscs. As AASTY is made by controlled radical polymerization techniques, the dispersity of polymer molecular weight distribution is low, and the molecular weights are controlled. This means that excess AASTY copolymer can be removed by dialysis after nanodisc formation. Based on previous findings on SMA, it is the expectation that AASTY of different molecular weights will display different rates of nanodisc formation, extraction efficacy, and stability of resulting nanodiscs.

Every membrane protein solubilization needs to undergo a screening process before. The characteristic phospholipid environment surrounding the different membrane proteins in question performs differently well with each polymer. To support you in this process, we offer a handy Screening Kit for AASTYs to test them all. Additionally, we recommend the two following publications if you would like to get further information: Smith et al. 2020 & Timcenko et al. 2022
