蛋白结构（Molecular Characterization）
This protein carries a flag tag at the N-terminus, followed by a polyhistidine tag, and a GFP tag at the C-terminus
The protein has a calculated MW of 54.0 kDa. The protein migrates as 22 kDa, 25 kDa, 51-52 kDa and 100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Nanodiscs are a new class of model membranes that are being used to solubilize and study a range of integral membrane proteins 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 nanodisc assembles from a mixture of full length membrane protein in detergent, phospholipid micelles and membrane scaffold protein(MSP1D1) upon removal of the detergent.

FACS Analysis of Non-specific binding to PBMCs
5e5 of PBMCs were stained with Fluorescent Human Claudin-6 Protein, Flag,His,GFP Tag (Cat. No. CL6-HF2M9) and anti-CD3 antibody, washed and then analyzed with FACS. PE signal was used to evaluate the expression of CD3+ T cells in PBMCs, and FITC signal was used to evaluate the non-specific binding activity to PBMCs (QC tested).
Protocol
背景（Background）
Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. These junctions are comprised of sets of continuous networking strands in the outwardly facing cytoplasmic leaflet, with complementary grooves in the inwardly facing extracytoplasmic leaflet. Claudin-6, also knows as CLDN6, is a multipass transmembrane protein in the Claudin family. Claudin-6 is expressed by epithelial cells where it participates in tissue development and the maintenance of tight junction integrity. And it is one of the entry cofactors for hepatitis C virus. The methylation of CLDN6 may be involved in esophageal tumorigenesis. The gene of CLDN6 is adjacent to another family member CLDN9 on chromosome 16.
