Scientific Background
The protein encoded by this gene is a type I transmembrane protein that belongs to the hemopoietin receptor superfamily. This protein binds to interleukine 12 (IL12) with a low affinity, and is thought to be a part of IL12 receptor complex. This protein forms a disulfide-linked oligomer, which is required for its IL12 binding activity. The coexpression of this and IL12RB2 proteins was shown to lead to the formation of high-affinity IL12 binding sites and reconstitution of IL12 dependent signaling. Mutations in this gene impair the development of interleukin-17-producing T lymphocytes and result in increased susceptibility to mycobacterial and Salmonella infections.

Safety & Handling
Research use only
This protein was produced in Mammalian (HEK293). Mammalian expression enables human-like glycosylation, correct disulfide bond formation, and proper protein folding — all critical for proteins used in binding interaction studies (SPR/BLI) and antibody characterisation. For transmembrane proteins expressed as ectodomains or nanodisc preparations, the expression system directly affects binding conformation and assay performance.
The molecular characterisation of this construct is: IL12RB1(Cys24-Glu540) 6×His tag. Cross-reference with the UniProt entry (P42701) to confirm the expressed region includes your domain of interest — receptor-binding domain, extracellular domain, or specific epitope — before ordering.
The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining.. A gel image showing the protein band is provided with each lot on the Certificate of Analysis. This high-purity specification is suitable for SPR/BLI kinetics measurements, ELISA standard curve development, and antibody epitope binding studies.
Please refer to the Certificate of Analysis (CoA) for reconstitution instructions for your specific lot. Storage: Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (A Prepare single-use working aliquots after reconstitution to avoid repeated freeze-thaw cycles. Lyophilized protein is stable for 12 months at −80°C from the date of receipt.
