Nanodiscs are a new class of model membranes that are being used to solubilize and study a range of integral membrane proteins (mp，full length CD20) and membrane-associated proteins. The Nanodisc bilayer is bounded by a membrane scaffold protein (MSP1D1) coat that confers enhanced stability and a narrow particle size distribution.
The CD20 nanodisc assembles from a mixture of full length CD20 protein in detergent, phospholipid micelles and membrane scaffold protein(MSP1D1) upon removal of the detergent.
The CD20 carries a polyhistidine tag at the C-terminus with calculated MW of 35.2 kDa and migrates as 40 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. The membrane scaffold protein（MSP1D1）has calculated MW of 24.7 kDa, and it migrates as 25 kDa under reducing (R) condition (SDS-PAGE) .
>85% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 20 mM HEPES, 150 mM NaCl, pH7.5 . Normally trehalose is added as protectant before lyophilization.
