Source

Human CD20 Full Length Protein-VLP (CDP-H52P6) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Pro 297 (Accession # P11836-1).

Predicted N-terminus: Met

Molecular Characterization

*The isotype control of empty/mock VLP (Cat. No. VLP-N5213) is sold separately and not included in protein, you can follow the link for product information.

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.

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.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>95% as determined by SEC-HPLC.

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, 0.2 M Arginine, pH7.4 with trehalose as protectant.

배경 소개

A B-lymphocyte surface antigen expressed from pre-B to mature B cells, but absent on plasma cells. It functions as a calcium channel and is a validated immunotherapy target, famously exploited by rituximab for treating B-cell malignancies and autoimmune disorders.
