Synonym
IFNGR1, CD119, CDw119, IFNGR, IFN-gamma-R1
Source
Human IFN-gamma R1, His Tag (IF1-H5223) is expressed from human 293 cells (HEK293). It contains AA Glu 18 - Gly 245 (Accession # AAH05333).
Predicted N-terminus: Glu 18
Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.6 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

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.
