分子别名（Synonym）
TNFRSF12A,FGF-inducible 14,FN14,TweakR,CD266
表达区间及表达系统（Source）
Human TWEAK R, Fc Tag (TNA-H526a) is expressed from human 293 cells (HEK293). It contains AA Glu 28 - Trp 79 (Accession # AAH02718).
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 32.5 kDa. The protein migrates as 38-40 kDa under reducing (R) condition, and 65-80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度（Purity）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.
