Fluorescent Virus-Like Particle (VLP) isotype control

  • Synonym
    VLP,Virus Like Particle,eVLP,VLPs
  • Source
    Fluorescent VLP isotype control(VLP-NF2P4) is expressed from human 293 cells (HEK293).
  • Molecular Characterization

    Virus-like particles(VLPs) are formed by self-assembly of envelop/capsid proteins from viruses. Membrance 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.

    Fluorescent VLP 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.

  • Conjugate

    GFP

    Excitation source: 488 nm spectral line, argon-ion laser

    Excitation Wavelength: 488 nm

    Emission Wavelength: 530 nm

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    The VLPs are highly immunogenic, so the immunization strategy should be optimized (antigen dose, regimen and adjuvant).

Identity-DLS
 VLP DLS

The mean peak Radius of VLP is 65-85 nm with more than 95% intensity as determined by dynamic light scattering (DLS).

  • 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.
