表达区间及表达系统（Source）
Human GDF-15, Fc Tag (GD5-H5269) is expressed from human 293 cells (HEK293). It contains AA Ala 197 - Ile 308 (Accession # Q99988-1).
Predicted N-terminus: Pro
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 38.8 kDa. The protein migrates as 45-55 kDa under reducing (R) condition, and 70-90 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
偶联（Conjugate）
Unconjugated
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
