Human IL1R2 / IL1RB / CD121b Protein

Species : Human

Synonyms : CD121b,CDw121b,IL-1R-2,IL-1RT-2,IL-1RT2,IL1R2c,IL1RB

Host : HEK293 Cells

Purity :> 95 % as determined by SDS-PAGE

Activity : 1. Measured by its binding ability in a functional ELISA. Immobilized Human IL1R2 (Cat: 10111-HCCH) at 2 £gg/ml (100 £gl/well) can bind Human IL-1 beta His (Cat: 10139-H07E), biotinylated, the EC50?of IL-1 beta His, biotinylated is 70-260 ng/mL.
2. Measured by its ability to inhibit Interferon gamma secretion by human natural killer lymphoma NK-92 cells in the presence of 500 pg/mL IL1b. The EC50 for this effect is typically 50-250 ng/mL.
