Synonyms
MSP1D1
Source
Nanodisc Biotinylated Human MSP1D1 Protein, His,Avitag is expressed from E. coli system. It contains AA Ser 1 - Gln 211.
Predicted N-terminus: Met
Request for sequenceMolecular Characterization
This protein carries an Avi tag (Avitag™) at the N-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 29.4 kDa. The protein migrates as 28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE). This protein is used together with nanodisc protein as isotype control.
Structure

Nanodisc membrane protein is wrapped by a synthetic phospholipid bilayer membrane structure, composed of membrane scaffold proteins (MSPs) and phospholipids.
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.
Protein Ratio
Passed as determined by the HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
Formulation
Supplied as 0.2 μm filtered solution in 20 mM HEPES, 150 mM NaCl, pH7.5 with trehalose as protectant.

SDS-PAGE

Biotinylated Human MSP1D1 Protein, His,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).
Bioactivity-FACS

2e5 of CD20-CAR-293 cells transfected with anti-CD20-scFv were stained with 100 μL of 10 μg/mL of Biotinylated Human MSP1D1 Protein, His,Avitag (Cat. No. APO-H81Q5), washed and then followed by PE-SA and analyzed with FACS. PE-SA was used as negative control (QC tested).

I received this product overnight and was able to use it in some SPR and Octet experiments. I was so happy to have found this product which is of good quality. I will continue to use this product along with the his-tagged version for different formats for assay development. I appreciate the option of having the biotinylated version of these empty nanodiscs as a control.
