GDF-15 Protein (Primary Amine Labeling), Human, Recombinant (hFc), Biotinylated

Catalog No. TMPK-00198

Growth and differentiation factor 15 (GDF15) is an inflammation-associated hormone with poorly defined biology. Here, we investigated the role of GDF15 in bacterial and viral infections. Inflammation induced GDF15, and that GDF15 was necessary for surviving both bacterial and viral infections, as well as sepsis. The protective effects of GDF15 were largely independent of pathogen control or the magnitude of inflammatory response, suggesting a role in disease tolerance. GDF-15 Protein (Primary Amine Labeling), Human, Recombinant (hFc), Biotinylated is expressed in HEK293 mammalian cells with N-hFc tag. The predicted molecular weight is 37.9 kDa and the accession number is Q99988.

Species	Human
Expression System	HEK293 Cells
Tag	N-hFc
Accession Number	Q99988
Synonyms	MIC-1,PTGFBPTGF-β,GDF15,PTGF-β,GDF-15,PTGF-beta,Placental TGF-beta,PTGFBPTGF-beta,NAG-1,RG-1,Placental TGF-β,PDF,PLAB,PTGFB,MIC1
Construction	Ala197-Ile308
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	37.9 kDa (predicted). Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.
Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
