表达区间及表达系统（Source）
Canine CD20 Full Length Protein (VLP) (CD0-C52P3) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Pro 297 (Accession # Q3C2E2-1).
Predicted N-terminus: Met 1
蛋白结构（Molecular Characterization）
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.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
制剂（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, Arginine, pH7.4 with trehalose as protectant.

活性（Bioactivity）-ELISA
Immobilized Canine CD20 Full Length Protein (VLP) (Cat. No. CD0-C52P3) at 2 μg/mL (100 μL/well) can bind Anti-CD20 antibody with a linear range of 0.01-0.625 μg/mL (QC tested).
Protocol
背景（Background）
This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. This protein can be used for screening and validation of dog CD20 antibody.
