- Molecular aliases
- IL23 alpha; IL12 beta; IL23 alpha&IL12 beta; IL12 β; IL23 alpha&IL12 β; IL-23A&IL-12B; IL23A&IL12B;IL12 b; IL12b; IL23 alpha&IL12 b; IL23 alpha&IL12b
- Protein length
- Arg20-Pro189
- Expression system
- HEK293
- Molecular weight
- The protein has a predicted MW of 21.7 kDa (IL-23 alpha) and 34.7 kDa (IL-12 beta). Due to glycosylation, the protein migrates to 24 kDa (IL-23 alpha) and 40-50 kDa (IL-12 beta) based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Formulation
- Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
