AASTY 11-45
Supplier: Cube Biotech
AASTYs (Acrylic acid-co-styrenes) - like AASTY 11-45 - are highly alternating copolymers, well-suited for the generation of native lipid nanodiscs. They are a 2022 novel developed series for membrane protein solubilization & stabilization. AASTY 11-45 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 6-45 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

SMALP BZ40 Membrane protein solubilization & stabilization
Supplier: Cube Biotech
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.

AASTY Screening Kit
Supplier: Cube Biotech
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.
