Recombinant Rat Il21, His tagged

Cat.No.: IL21-378R
Product Overview: Recombinant Rat Il21 (NP_001102413.1) (Met1-Ser146), fused with a polyhistide tag at the C-terminus, was produced in Baculovirus-Insect cells.
Source: Baculovirus-Insect cells
Species: Rat
Tag: His
Predicted N Terminal: His 18
Form: Lyophilized from sterile 20mM Tris, 500mM NaCl, 10% glycerol, pH 7.4.Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization.
Molecular Mass: The recombinant rat IL21 consists of 139 amino acids and predicts a molecular mass of 16.6 KDa. It migrates as an approximately 20 KDa band in SDS-PAGE under reducing conditions.
Endotoxin: < 1.0 eu per μg of the protein as determined by the LAL method.
Purity: >90 % as determined by SDS-PAGE
Stability: Samples are stable for up to twelve months from date of receipt at -70oC.
Storage: Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: 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.
