Recombinant mature form of human IDO2 (Q6ZQW0-1) (Met 1-Gly 407) was fused with a polyhistidine tag at the C-terminus.
Predicted N Terminal:
Lyophilized from sterile PBS, 20% glycerol, pH 7.5, 5%~8% trehalose and mannitol.
The recombinant human IDO2 comprises 413 amino acids and has a calculated molecular mass of 46.2 KDa. It migrates as an approximately 43 kDa band in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>93 % 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.
