Active Recombinant Rat Il9r, His-tagged

• Cat.No.: Il9r-538R
• Product Overview: Recombinant Rat Il9r (Accession # EDM04022) Val38-Ala270, fused with a C-terminal 6-His tag, was produced in Mouse myeloma cell line, NS0-derived.

Specification

• Source: Mammalian cells
• Species: Rat
• Tag: His
• Predicted N Terminal: Val38
• Form: Lyophilized from a 0.2 µm filtered solution in PBS with BSA as a carrier protein.
• Bio-activity: Measured by its ability to inhibit IL-9-induced proliferation of TS1 mouse helper T cells.The ED50 for this effect is typically 0.25 - 1.25 µg/mL in the presence of rrIL-9 at 50 ng/mL.
• Molecular Mass: Recombinant Rat Il9r, His-tagged has a calculated MW of 27.5 kDa. In SDS-PAGE migrates as 33-40 kDa, reducing conditions.
• Purity: >95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4ºC); After reconstitution under sterile conditions for 3 months (-70ºC).
• Reconstitution: Reconstitute at 200 µg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.
