Fluorescent Virus-Like Particle (VLP) Protein Isotype Control (VLP-NF2P4) is expressed from human 293 cells (HEK293).
蛋白结构（Molecular Characterization）
Fluorescent Virus-Like Particle (VLP) Protein Isotype Control (VLP-NF2P4) carries a GFP tag and is formed by self-assembly of envelop/capsid proteins from viruses, it can be used as isoytype control for Fluorescent VLPs displaying membrane proteins in various applications.
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.

背景（Background）
Virus-like particles (VLPs) are highly structured protein particles composed of single or multiple structural proteins of the virus. Its morphological structure is similar to that of natural virus particles, does not contain virus accounting, and has strong immunogenicity and biological activity. The empty shell structure of most VLP is icosahedral or helical structure, which is composed of several specific structural proteins. At present, it is widely used in vaccine production and antigen presentation.
