Source:Spodoptera frugiperda, Sf 21 (baculovirus)-derived
Accession #:Q4FK69
N-terminal Sequence Analysis:Phe14
Structure:Disulfide-linked homodimer
Purity:>95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Predicted Molecular Mass:64.7 kDa (monomer)
SDS-PAGE:70-80 kDa, reducing conditions
Activity:Measured by its ability to inhibit IL-1 alpha -dependent proliferation in D10.G4.1 mouse helper T cells. Symons, J.A. et al. (1987) in Lymphokines and Interferons, a Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 272.
Approximately 2 - 8 µg/mL of IL-1 RII will inhibit 50% of the biological response due to 50 pg/mL of recombinant mouse IL-1 alpha.
Formulation:Lyophilized from a 0.2 µm filtered solution in PBS. See Certificate of Analysis for details.

N-terminus C-terminus
What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

Reconstitution:
Reconstitute at 500 µg/mL in sterile PBS.

Shipping:
The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.

Stability & Storage:
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 12 months from date of receipt, -20 to -70 °C as supplied.
  • 1 month, 2 to 8 °C under sterile conditions after reconstitution.
  • 3 months, -20 to -70 °C under sterile conditions after reconstitution.
