SMALP Screening Set (4x3x50 mg)

Membrane protein and their composition as as versatile as the whole cell membrane itself. For this reason it is sadly impossible to predict with a 100% accuracy which SMALP product is suited best for the solubilization & subsequent of your membrane protein of interest.
For this reason we offer this SMALP Screening Kit that consists of our four individual SMAs. This way you have a convenient way to screen for the best SMA for your protein before scaling up your assay.
In case you would like to extend your polymer screening beyond the reaches of SMA we offer our Synthetic Nanodisc Screening Kit, that covers both SMA and DIBMA.

Figure 1 shows the necessity for a SMALP screen instead of using a random SMALP product. Note that the detergent LMNG may provide the mighest protein yield, but it has to be added to the purified protein constantly and it might interfere with the SPIKE protein's function.
