表达区间及表达系统（Source）
Human CD63 Full Length Protein (VLP) (CD3-H52P6) is expressed from human 293 cells (HEK293). It contains AA Ala 2 - Met 238 (Accession # P08962).
Predicted N-terminus: Met
蛋白结构（Molecular Characterization）
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.
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 CD63 Full Length Protein (VLP) (Cat. No. CD3-H52P6) at 0.1 ug/well (100 μL/well) can bind Anti-CD63 Antibody 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 55-75 nm with more than 95% intensity as determined by dynamic light scattering (DLS).
背景（Background）
Functions as a cell surface receptor for TIMP1 and plays a role in the activation of cellular signaling cascades. Plays a role in the activation of ITGB1 and integrin signaling, leading to the activation of AKT, FAK/PTK2 and MAP kinases. Promotes cell survival, reorganization of the actin cytoskeleton, cell adhesion, spreading and migration, via its role in the activation of AKT and FAK/PTK2. Plays a role in VEGFA signaling via its role in regulating the internalization of KDR/VEGFR2. Plays a role in intracellular vesicular transport processes, and is required for normal trafficking of the PMEL luminal domain that is essential for the development and maturation of melanocytes. Plays a role in the adhesion of leukocytes onto endothelial cells via its role in the regulation of SELP trafficking. May play a role in mast cell degranulation in response to Ms4a2/FceRI stimulation, but not in mast cell degranulation in response to other stimuli.
