- Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 14.2 kDa. the protein migrates as 16-17 kDa under reducing (R) condition, and 27 kDa under non-reducing (NR) condition (SDS-PAGE).
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by reduced SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in 60% ACN, 0.085% TFA. Normally trehalose is added as protectant before lyophilization.

Human GDF-15, His Tag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
Immobilized Human GDF-15, His Tag (Cat. No. GD5-H5149) at 1 μg/mL (100 μL/well) can bind Human GFR alpha-like Fc Chimera Protein with a linear range of 0.2-8 ng/mL (QC tested).
- BackgroundGrowth Differentiation Factor 15 (GDF-15), also called Macrophage Inhibitory Cytokine 1 (MIC-1). Expression of MIC-1 mRNA in monocytoid cells is up-regulated by a variety of stimuli associated with activation, including interleukin 1β, tumor necrosis factor α (TNF-α), interleukin 2, and macrophage colony-stimulating factor but not interferon γ, or lipopolysaccharide (LPS). It is highly expressed in cardiomyocytes, adipocytes, macrophages, endothelial cells, and vascular smooth muscle cells in normal and pathological condition. GDF-15 increases during tissue injury and inflammatory states and is associated with cardiometabolic risk. Increased GDF-15 levels are associated with cardiovascular diseases such as hypertrophy, heart failure, atherosclerosis, endothelial dysfunction, obesity, insulin resistance, diabetes, and chronic kidney diseases in diabetes. Increased GDF-15 level is linked with the progression and prognosis of the disease condition.
