Active Recombinant Rat Il9

• Cat.No.: Il9-676R
• Product Overview: Recombinant Rat Il9 (Accession # NP_001099217) Gln19-Ala144 was produced in Mouse myeloma cell line, NS0-derived.

Specification

• Source: Mammalian cells
• Species: Rat
• Predicted N Terminal: Gln19
• Form: Lyophilized from a 0.2 µm filtered solution in Acetonitrile and TFA with BSA as a carrier protein.
• Bio-activity: Measured in a cell proliferation assay using TS1 mouse helper T cells. Uyttenhove, C. et al. (1988) Proc. Natl. Acad. Sci. 85:6934. The ED50 for this effect is typically 3-15 ng/mL.
• Molecular Mass: Recombinant Rat Il9 has a calculated MW of 14.1 kDa. In SDS-PAGE migrates as 30-35 kDa, reducing conditions.
• Purity: >90%, 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 10 µg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.
