Product Properties Synonyms IL23 alpha; IL12 β; IL23 alpha&IL12 beta ; Source Cynomolgus IL-23 alpha&Mouse IL-12 beta Protein is expressed from HEK293 with His tag at the N-Terminu s. It contains Val22-Pro189(Cynomolgus IL-23 alpha)&Met23-Ser335(Mouse IL-12 beta).[Accession | A0A2K5TLV4-1(Cynomolgus IL-23 alpha)&P43432-1(Mouse IL-12 beta)] Molecular Weight The protein has a predicted MW of 19.5 (Cynomolgus IL23 alpha)&35.8 (Mouse IL12 beta) kDa. Due to glycosylation, the protein migrates to 22 (Cynomolgus IL23 alpha)&40-50 (Mouse IL12 beta) kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity SPR Data: Cynomolgus IL-23R, His Tag immobilized on CM5 Chip can bind Cynomolgus IL-23 alpha&Mouse IL-12 beta, His Tag with an affinity constant of 3.90 nM as determined in SPR assay . Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 -6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
