表达区间及表达系统（Source）
Human PTH1R Full Length Protein (VLP) (PTR-H52P3) is expressed from human 293 cells (HEK293). It contains AA Asp 27 - Met 593 (Accession # Q03431).
Predicted N-terminus: Asp
蛋白结构（Molecular Characterization）
Virus-like particles(VLPs) are formed by self-assembly of 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 / rFC method.
纯度（Purity）
>95% as determined by SEC-HPLC.
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.
