Recombinant human PTPN9 (NP_002824.1) (Ala285-Gln593) was expressed with a C-terminal polyhistidine-tagged GST tag at the N-terminus (his-GST).
Predicted N Terminal:
Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 10 % glycerol, pH 8.0, 5%~8% trehalose and mannitol.
The recombinant human PTPN9 consists 546 amino acids and predicts a molecular mass of 63.3 kDa.
< 1.0 EU per μg of the protein as determined by the LAL method.
>90 % as determined by SDS-PAGE.
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 of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
