|Interleukin-23 (IL23A & IL12B Heterodimer)|
|A DNA sequence encoding the mouse IL23A (Q9EQ14) (Met1-Ala196 ) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding mouse IL12B (P43432) (Met1-Ser335) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the mouse IL23 heterodimer was purified.|
|In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.|
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
|(33.1+31.5+32.9) % as determined by SDS-PAGE|
|Measured by its binding ability in a functional ELISA.|
1. Measured by its ability to bind recombinant rat IL23R-Fc (Cat:80395-R02H) in a functional ELISA.
2. Immobilized mouse IL12Bh (m)+mIL23Ah at 10 μg/ml (100 μl/well) can bind human IL23R-Fc (Cat:13840-H02H). The EC50 of human IL23R-Fc (Cat:13840-H02H) is 0.14-0.35 μg/ml.
3.Immobilized mouse IL12Bh (m)+mIL23Ah at 10 μg/ml (100 μl/well) can bind Cynomolgus IL23R-Fc (Cat:90123-C02H). The EC50 of Cynomolgus IL23R-Fc (Cat:90123-C02H) is 0.05-0.11 μg/ml.
4.Immobilized mouse IL12Bh (m)+mIL23Ah at 10 μg/ml (100 μl/well) can bind biotinylated human IL12RB1-His (Cat:11674-H08H). The EC50 of biotinylated human IL12RB1-His (Cat:11674-H08H) is 21.3-49.8 ng/mL.
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|Val 22 & Met 23|
|The recombinant mouse IL23 (mouse IL23A&IL12B Heterodimer) comprises 510 (186+324) amino acids and has a calculated molecular mass of 58.3 (21.1+ 37.2) KDa. The apparent molecular mass of the recombinant protein is approximately 47,45 and 26 KDa respectively in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile PBS, pH 7.4. |
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
