Active Recombinant Rabbit IL4, Met-tagged

• Cat.No.: IL4-698R
• Product Overview: Recombinant Rabbit IL4 (Accession # NP_001156649) Arg25-Ser147, fused with an N-terminal Met, was produced in E. coli-derived.

Specification

• Source: E. coli
• Species: Rabbit
• Predicted N Terminal: Met
• Form: Lyophilized from a 0.2 µm filtered solution in PBS with BSA as a carrier protein.
• Bio-activity: Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323.The ED50 for this effect is typically 3 - 15 ng/mL.
• Molecular Mass: Recombinant Rabbit IL4, Met-tagged has a calculated MW of 14.2 kDa. In SDS-PAGE migrates as 12.5 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 100 µg/mL in PBS containing at least 0.1% human or bovine serum albumin.
