Synthetic nanodisc products


Dibma with protein
Synthetic nanodiscs are disc shaped complexes made from synthetic polymers like DIBMA or SMAs (1,2) that are one the best ways to solubilize and stabilize a membrane protein of interest. Their development and use in the field of proteomics is one of the greatest advances pf the field. Traditionally Detergents (like SDS, n-octyl-β-d-glucopyranoside (OG), n-dodecyl-β-d-maltoside (DDM) are used for solubilization and stabilization of membrane proteins from the cell membrane. However these detergents can interfere with affect the functional properties of a membrane protein (3). Synthetic nanodiscs are mimicing the native lipid membrane by cutting out the membrane protein of interest out of the cell membrane together with its original lipid enviroment. The alternative to Synthetic Nanodiscs are the MSP-nanodiscs.
Update November 2020: We added SMA to our product assortment! With the help of Orbiscope we now offer a second options to create synthetic nanodiscs for membrane protein solubilization & stabilization!
Currently these are CubeBiotech's options for the creation of synthetic nanodiscs:

DIBMA

Structure
Note that this is the default structure for most SMAs, but not all. For example SMALP 1100I is imidized.
SMA Structure
DIBMA is the perfect choice for membrane protein solubilization and subsequent stabilization without the need for detergents (4). One further advantage of DIBMA is the lack of any meaningful absorbance of the protein specific wavelength of 280 nm. Therefore quantifying a protein after treatment with DIBMA is not influenced by any absorbance signal by the polymer.
Similar to DIBMA, SMA is a synthetic polymer that can create synthetic nanodiscs for the solubilization & stabilization for membrane proteins. The key difference between the two lies in the superior solulization rate of SMA compared to DIBMA. However SMA shows noticeable absorbance at 280 nm.
SMA or DIBMA
The question if SMA or DIBMA is the best option for your protein of interest is a tricky one. Especially if you have never worked with your current membrane protein of interest before. For these cases we compiled our most prominent SMALP and DIBMA products into this practical Synthetic Nanodisc Screening Set for your convenience!
All 8 products are buffered in HEPES to provide maximal comparability between the individual screening assays. Which 8 products are include in the Kit precisely can be found in the product's description.
