Source

Nanodisc Biotinylated Cynomolgus CD20 Full Length Protein, His,Avitag (CD0-C82E4) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Pro 297 (Accession # M4ZHZ6-1 ).

Predicted N-terminus: Met 1

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 36.9 kDa. The protein migrates as 24-25 kDa and 40-41 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

*The isotype control of empty/mock nanodisc (Cat. No. APO-H81Q5) is sold separately and not included in protein, you can follow the link for product information.

1. Structure

   

   Nanodisc membrane protein is wrapped by a synthetic phospholipid bilayer membrane structure, composed of membrane scaffold proteins (MSPs) and phospholipids.

2. Synthesis Process

   

   Nanodisc reconstitution is a self-assembly process that starts from purified, detergent-solubilized membrane proteins and reconstitutes them into synthetic phospholipid bilayers stabilized by MSP1D1 membrane scaffold protein. This creates a stable, detergent-free environment that preserves native conformation and biological activity, with excellent homogeneity and full compatibility with cell-based assays such as FACS and binding assays in antibody discovery and screening (ELISA),etc.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
