表达区间及表达系统(Source)

Fluorescent Human SSTR2 Full Length Protein (VLP) (SS2-HF2G3) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Ile 369 (Accession # P30874-1).

Predicted N-terminus: Asp

蛋白结构(Molecular Characterization)

This protein carries a GFP tag.

The protein has a calculated MW of 45.3 kDa | 83.1 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.

偶联(Conjugate)

GFP

Excitation source: 488 nm spectral line, argon-ion laser

Excitation Wavelength: 488 nm

Emission Wavelength: 530 nm

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

SSTR2 ELISA

Immobilized Fluorescent Human SSTR2 Full Length Protein (VLP) (Cat. No. SS2-HF2G3) at 1 μg/mL (100 μL/well) can bind Anti-SSTR2 Antibody, Human IgG1 with a linear range of 0.1-4 ng/mL (QC tested).

Protocol

 

均一性(Identity)-DLS

SSTR2 DLS

The mean peak Radius of VLP is 55-75 nm with more than 95% intensity as determined by dynamic light scattering (DLS).

 

背景(Background)

Somatostatin is a peptide with a potent and broad antisecretory action, which makes it an invaluable drug target for the pharmacological management of pituitary adenomas and neuroendocrine tumors. Somatostatin receptors (SSTR1, 2A and B, 3, 4 and 5) belong to the G protein coupled receptor family and have a wide expression pattern in both normal tissues and solid tumors. Investigating the function of each SSTR in several tumor types has provided a wealth of information about the common but also distinct signaling cascades that suppress tumor cell proliferation, survival and angiogenesis. This provided the rationale for developing multireceptor-targeted somatostatin analogs and combination therapies with signaling-targeted agents such as inhibitors of the mammalian (or mechanistic) target of rapamycin (mTOR). The ability of SSTR to internalize and the development of rabiolabeled somatostatin analogs have improved the diagnosis and treatment of neuroendocrine tumors.
