蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 52.4 kDa. The protein migrates as 60-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

电泳（SDS-PAGE）
Human IFN-gamma R1, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
活性（Bioactivity）-ELISA
Immobilized Human IFN-gamma, premium grade (Cat. No. IFG-H4211) at 5 μg/mL (100 μL/well) can bind Human IFN-gamma R1, Fc Tag (Cat. No. IF1-H5254) with a linear range of 0.1-6 ng/mL (QC tested).
Protocol
背景（Background）
Interferon gamma receptor 1 (IFNGR1) is also known as CD antigen CD119, which belongs to the type II cytokine receptor family. IFNGR1 contains two fibronectin type-III domains and two Ig-like C2-type (immunoglobulin-like) domains. IFNGR1 / CD119 is receptor for interferon gamma. Two receptors bind one interferon gamma (IFNG) dimer.
