Human Claudin-1 Full Length Protein (VLP) (CL1-H52P6) is expressed from human 293 cells (HEK293). It contains AA Met 1 -Val 211 (Accession # O95832).
Predicted N-terminus: Met 1
蛋白结构（Molecular Characterization）
The protein has a calculated MW of 24.6 kDa | 56.1 kDa.
Virus-like particles(VLPs) are formed by self-assembly of envelop/capsid proteins from viruses. Membrane Proteins can be constituted in-situ with VLPs produced from HEK293 cell cultures. These VLPs concentrate conformationally intact membrane proteins directly on the cell surface and produce soluble, high-concentration proteins perfect for immunization and antibody screening.
The VLPs provide the display of properly folded membrane proteins in their native cellular membrane in a compact size of 100~300 nm diameter (similar to the size of most viruses) making it optimal targets for dendritic cells in vivo and surface attachment for phage display.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
制剂（Formulation）
The VLPs are highly immunogenic, so the immunization strategy should be optimized (antigen dose, regimen and adjuvant).
Supplied as 0.2 μm filtered solution in PBS, Arginine, pH7.4 with trehalose as protectant.

活性（Bioactivity）-ELISA
Immobilized Human Claudin-1 Full Length Protein (VLP) (Cat. No. CL1-H52P6) at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-Human Claudin-1 antibody, Human IgG1 with a linear range of 0.3-20 ng/mL (QC tested).
Protocol
均一性（Identity）-DLS
The mean peak Radius of VLP is 60-80 nm with more than 95% intensity as determined by dynamic light scattering (DLS).
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. The protein encoded by this gene, a member of the claudin family, is an integral membrane protein and a component of tight junction strands. Loss of function mutations result in neonatal ichthyosis-sclerosing cholangitis syndrome. [provided by RefSeq, Jul 2008]
