The synthethic polymer SMALP 140, among our other synthetic nanodisc products has been developed for for the solubilization & subsequent purification of membrane proteins from all kinds of cell membranes. SMALP products do this by using the phospholipids around the membrane proteins and form them into a disc-shaped structure in which the membrane proteins are centered.
SMALP 140 + its corresponding buffer are shipped in a lyophilized state, so they have to be dissolved in dH2O. Then the product is ready-to-use. SMALP 140 has a amber color in solution.
We recommend using affinity chromatography for the follow-up purification of the membrane protein of interest. The Rho1D4-tag has proven to be especially usefull for membrane protein purification. Cube Biotech offers the matching products for this purpose.
SMALP Screening: Different membrane protein usually perform different under different SMAs variants respectively. To ease the resulting screening process we compiled all of our SMAs into a convenient SMALP Screening Set.
Furthermore if you like to compare proteins's performance between DIBMA and SMA, we also offer our, that includes both our SMA and DIBMA products.
