表达区间及表达系统（Source）
Human GCGR Full Length Protein (VLP) (GCR-H52P5) is expressed from human 293 cells (HEK293). It contains AA Ala 26 - Asn 432 (Accession # P47871-1).
Predicted N-terminus: Asp
蛋白结构（Molecular Characterization）
The protein has a calculated MW of 91.0 kDa | 56.1 kDa.
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.

背景（Background）
The protein encoded by this gene is a glucagon receptor that is important in controlling blood glucose levels. Defects in this gene are a cause of type 2 diabetes mellitus (T2DM) . The ever increasing prevalence of type 2 diabetes mellitus in the developed and developing nations calls for the introduction of new and more effective treatments. Glucagon receptor (GCGR) antagonists are highly validated in preclinical models of T2DM and thus have the potential to be developed as a new therapy.
