Human CXCR5 Full Length Protein-VLP (HEK293)

  • Source
    Human CXCR5 Full Length Protein-VLP(CX5-H52P4) is expressed from human 293 cells (HEK293). It contains AA Asn 2 - Phe 372 (Accession # P32302-1 ).
    Predicted N-terminus: Asp
  • 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.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • 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, pH7.4 with trehalose as protectant.

    Contact us for customized product form or formulation.

Bioactivity-ELISA
 CXCR5 ELISA

Immobilized Human CXCR5 Full Length Protein-VLP (Cat. No. CX5-H52P4) at 5 μg/mL (100 μL/well) can bind Monoclonal Anti-Human CXCR5 antibody, Human IgG4 | Human Kappa with a linear range of 1-78 ng/mL (QC tested).

Identity-DLS
 CXCR5 DLS

The mean peak Radius of VLP is 60-75 nm with more than 95% intensity as determined by dynamic light scattering (DLS).

  • Background
    This gene encodes a multi-pass membrane protein that belongs to the CXC chemokine receptor family. It is expressed in mature B-cells and Burkitts lymphoma. This cytokine receptor binds to B-lymphocyte chemoattractant (BLC), and is involved in B-cell migration into B-cell follicles of spleen and Peyer patches. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2011]
