表达区间及表达系统（Source）
Human GLP1R Full Length Protein (L260F), Flag,His Tag (GLR-H52D4) is expressed from human 293 cells (HEK293). It contains AA Arg 24 - Ser 432 (Accession # P43220-1(L260F)).
Predicted N-terminus: Asp
蛋白结构（Molecular Characterization）
This protein carries flag tag at the N-terminus and polyhistidine tag at the C-terminus.
The protein has a calculated MW of 66.5 kDa.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
制剂（Formulation）
This product is not suitable for cell based experiments due to cytotoxicity of DDM.
DDM and CHS are INDISPENSABLE to keep membrane protein soluble and active, under no circumastance should you remove DDM and CHS.
DDM/CHS buffer (DC-11) is sold separately and not included in protein, and please contact us if you need the buffer.
If glycerol is not compatible to your application, remove glycerol just before immediate experiment, and NEVER store glycerol-free protein solution.
Supplied as 0.2 μm filtered solution in 50 mM HEPES, 150 mM NaCl, DDM, CHS, pH7.5 with glycerol as protectant.

活性（Bioactivity）-ELISA
Immobilized Human GLP1R Full Length Protein, Flag,His Tag (Cat. No. GLR-H52D4) at 5 μg/mL (100 μL/well) on a Nickel Coated plate (Cat. No. SP-16) can bind GLP1R agonist with a linear range of 0.5-16 ng/mL (QC tested).
Protocol
活性（Bioactivity）-SPR
GLP1R agonist captured on Protein A Chip can bind Human GLP1R Full Length Protein, Flag, His Tag (Cat. No. GLR-H52D4) with an affinity constant of 2.74 µM as determined in a SPR assay (in presence of DDM and CHS) (Biacore 8K) (Routinely tested).
Protocol
背景（Background）
This gene encodes a 7-transmembrane protein that functions as a receptor for glucagon-like peptide 1 (GLP-1) hormone, which stimulates glucose-induced insulin secretion. This receptor, which functions at the cell surface, becomes internalized in response to GLP-1 and GLP-1 analogs, and it plays an important role in the signaling cascades leading to insulin secretion. It also displays neuroprotective effects in animal models. Polymorphisms in this gene are associated with diabetes. The protein is an important drug target for the treatment of type 2 diabetes and stroke.
