Recombinant human NPM1 isoform 1 (P06748-1) (Glu2-Leu294) was expressed with a polyhistide tag at the N-terminus.
Predicted N Terminal:
Lyophilized from sterile 30 mM Hepes, 2 mM EDTA, 0.001 % Tween, 15 % glycerol, pH 7.0, 5%~8% trehalose and mannitol.
The recombinant human NPM1 consists of 304 amino acids and has a calculated molecular mass of 34 kDa.
< 1.0 EU per μg of the protein as determined by the LAL method.
>85 % 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.
