Fluorescent Virus-Like Particle (VLP) Protein Isotype Control

Application

1. Immunization
2. Cell based assay (FACS or functional assay)
3. Screening (ELISA)

Synonyms

VLP, Virus Like Particle, eVLP, VLPs

Source

Fluorescent Virus-Like Particle (VLP) Protein Isotype Control (VLP-NF2P4) is expressed from human 293 cells (HEK293).

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.

1. Structure

   

   Virus-like particles (VLPs) are protein particles that mimic the shape of viruses but lack a viral genome, and incorporating transmembrane proteins on the external surface.

2. Synthesis Process

   

   Envelope virus-like particles (eVLPs) are produced by co-expressing target membrane proteins with viral structural proteins in mammalian cells, enabling native embedding of membrane proteins into the lipid bilayer during VLP budding. This approach preserves authentic conformation, post-translational modifications, and orientation, while creating a completely detergent-free environment with repetitive multivalent display and strong immunogenicity making them ideal for immunization, binding assays in antibody discovery and screening (ELISA), and cell-based assays such as FACS, etc.

Conjugate

GFP
