Source:Spodoptera frugiperda, Sf 21 (baculovirus)-derived
N-terminal Sequence Analysis:Phe14
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.
