Recombinant Human NGF mature form (NP_002497.2) (Ser 122-Arg 239), fused with no tag, was produced in CHO Cells.
Lyophilized from sterile 20mM NaAc, 150mM NaCl, pH 5.5
The mature recombinant human β-NGF consists of 118 amino acids and has a predicted molecular mass of 13.2 kDa. β-NGF exists as a non-disulfide linked homodimer in solution.
< 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.
