Active Recombinant Rat Il9 Protein, His-tagged

• Cat.No.: Il9-1117R
• Product Overview: Recombinant rat Il9 (NP_001099217.1) (Met1-Ala144) was expressed with a polyhistidine tag at the C-terminus.

Specification

• Species: Rat
• Source: Insect Cells
• Tag: His
• Protein Length: 1-144 a.a.
• Predicted N Terminal: Gln 19
• Form: Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 10 % glycerol, 5%~8% trehalose and mannitol.
• Bio-activity: Measured in a cell proliferation assay using MC/9-2 mouse mast cells. The ED50 for this effect is typically 19.8-79.2 ng/mL.
• Molecular Mass: The recombinant rat Il9 consists 137 amino acids and predicts a molecular mass of 15.6 kDa.
• 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 of 0.25 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
