||Recombinant Human DDOST (P39656-1) extracellular domain (Ser 43-Pro 427), fused with two additional amino acids (Gly & Pro) at the N-terminus, was produced in E. coli.
||Lyophilized from sterile 50mM Tris, 150mM NaCl, pH 8.0
||The recombinant human DDOST consists of 387 amino acids and has a calculated molecular mass of 42.7 kDa. It migrates as an approximately 46 kDa band in SDS-PAGE under reducing conditions.
||< 1.0 eu per μg of the protein as determined by the LAL method.
||Samples are stable for up to twelve months from date of receipt at -70oC.
||Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
||It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4oC before opening to recover the entire contents.
