Application of SMALP in Screening of Different Membrane Proteins
Description
The SMALP, among all synthetic nanodisc products has been developed for for the solubilization of membrane proteins from all kinds of cell membranes and subsequent isolation & purification of said membrane proteins. After dissolving SMALP 200 + buffer powder in dH2O, the product is ready-to-use. SMALP 200 has a yellowish color in solution. After successfull solubilization of the membrane protein, the protein can be purified using affinity chromatography. For membrane protein purification we recommed to use the Rho1D4-tag. Cube Biotech offers the matching products for this purpose.

Lab Results
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 SMA and DIBMA in synthetic nanodiscs, we also offer our, that includes both our SMA and DIBMA products.
