AASTY 6-55

Supplier: CUBE BIOTECH
Description: 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

5,5'-difluoro BAPTA tetrapotassium salt ≥95% (by TLC) ion chelator, for calcium determination

Catalog Number: (89139-166)
Supplier: Biotium
Description: BAPTA and its derivatives are calcium chelators that are commonly used to form calcium buffers with well-defined calcium concentrations. By injecting the chelators into cells or by incubating cells with the AM ester form of the chelators, one can control the cytosolic calcium concentration, an important means to study the roles of calcium.

Mouse Recombinant IL-22 (from E. coli cells)

Supplier: VWR International
Description: Interleukin 22 (IL-22), also called IL-TIF, is an IL-10 family member that is produced by activated dendritic cells and T lymphocytes. IL-22 signals via a heteroduplex receptor consisting of IL-22R and IL-10RB chains. IL-22 is a potent mediator of cellular inflammatory responses and wound healing.
