Endotoxin:
< 1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by Tris-Bis PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of 50 mM HAc (pH 2.9). Contact us for customized product form or formulation.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile 50 mM HAc (pH 2.9). Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
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.
Recombinant Human GDF15 Protein was determined by Tris-Bis PAGE under reducing (R) and non-reducing (NR) conditions.
Immobilized Human GDF15, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human GFRAL, hFc Tag with the EC50 of 22.8ng/ml determined by ELISA.
Serial dilutions of Anti-GDF15 Antibody were added into Human GDF15, His Tag: Biotinylated Human GFRAL, His Tag binding reactioins. The half maximal inhibitiory concentration (IC50) is 40.8ng/ml.
