Human IL-23A & mouse IL-12B Heterodimer

• Catalog Number: orb2993931
• Category: Proteins
• Description: Recombinant Chimeric Human&Mouse Interleukin-23 is produced by our Mammalian expression system and the target gene encoding Arg20-Pro189&Met23-Ser335 is expressed with a 6His tag at the C-terminus.
• Conjugation: Unconjugated
• Tag: C-6His
• Form/Appearance: Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
• Reconstitution: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Purity: SDS-PAGE: Greater than 95% as determined by reducing SDS-PAGE.
• UniProt ID: Q9NPF7, P43432
• MW: Predicted: 56.9 KDa. Observed: 65-80 KDa, reducing conditions
• Expression System: Human Cells
• Endotoxins: < 1 EU/µg as determined by LAL test.
• Biological Origin: Human&Mouse
• Biological Activity: ELISA: Immobilized Human IL-23R-Fc(Cat#orb2994313) at 10μg/ml (100 μl/well) can bind Human IL-23A & mouse IL-12B Heterodimer-His(Cat#orb2993931). The ED50 of Human IL-23A & mouse IL-12B Heterodimer-His(Cat#orb2993931) is 0.48 ug/ml. Immobilized Human IL-23A & mouse IL-12B Heterodimer-His(Cat#orb2993931) at 2μg/ml (100 μl/well) can bind Anti-Human IL23-P19 mAb(Cat#orb2993116).The ED50 of Anti-Human IL23-P19 mAb(Cat#orb2993116) is 7.47 ng/ml.. BLI: Loaded Human IL-23R-Fc(Cat#orb2994313) on Protein A Biosensor, can bind Human IL-23A & mouse IL-12B Heterodimer-His(Cat#orb2993931) with an affinity constant of 9.48 nM as determined in BLI assay. Loaded Anti-Human IL23-P19 mAb-Fc(Cat#orb2993116) on Protein A Biosensor, can bind Human IL-23A & mouse IL-12B Heterodimer-His(Cat#orb2993931) with an affinity constant of -3 nM as determined in BLI assay. . Cell Based Assay: Measured by its ability to induce STAT reporter activity in 293F human embryonic kidney cells. The ED50 for this effect is 357.68 ng/ml.
• Expression Region: Arg20-Pro189&Met23-Ser335
