Lyophilized
Reconstitution
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/mL is recommended. Dissolve the lyophilized protein in 50 mM HAc ( pH 2.9).
Buffer
Lyophilized from 0.22μm filtered solution in 50 mM HAc ( pH 2.9). Normally 8 % trehalose is added as protectant before lyophilization.

Stockage commentaire
-20 to -80°C for 12 months as supplied from date of receipt.,-80°C for 3-6 months after reconstitution.,2-8°C for 2-7 days after reconstitution.,Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Growth Differentiation Factor 15 (GDF15), also known as NSAID activated gene-1 (NAG-1), is associated with a large number of biological processes and diseases, including cancer and obesity. GDF15 is synthesized as pro-GDF15, is dimerized, and is cleaved and secreted into the circulation as a mature dimer GDF15.
Poids moléculaire
13.12 kDa. The protein migrates to 15-20 kDa under reduced (R) condition and 23-26 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.
