Application

Human IL-23A&IL-12B Heterodimer Protein, His Tag&Tag Free AIDD-Ready protein is designed for direct use in SPR assays. It is supplied in a sugar-free, glycerol-free formulation to eliminate refractive index interference in SPR. No desalting or buffer exchange is required before use, simplifying the SPR workflow and supporting high-throughput experimental validation to accelerate the transition from AI prediction to wet-lab validation.

Features and Advantages
  • Directly compatible with SPR: No desalting or buffer exchange required; supplied as a liquid to reduce sample preparation and improve experimental efficiency.
  • High batch-to-batch consistency: Each lot is released using SPR QC to ensure experimental reproducibility.
  • Validated with representative drugs: SPR binding activity is validated using representative drug antibodies to ensure suitability for drug screening and evaluation.
Synonyms

IL-23 alpha & IL-12 beta

Source

Human IL-23A&IL-12B Heterodimer Protein, His Tag&Tag Free (ILB-H52W5AI) is expressed from human 293 cells (HEK293). It contains AA Arg 20 - Pro 189 (IL23A) & Ile 23 - Ser 328 (IL12B) (Accession # Q9NPF7-1 (IL23A) & P29460-1 (IL12B)).

Predicted N-terminus: His (IL23A) & Ile 23 (IL12B)

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

The protein has a calculated MW of 19.5 kDa (IL23A) & 34.7 kDa (IL12B). The protein migrates as 19-20 kDa, 37-39 kDa and 41-42 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a heterodimer.

Purity

>90% as determined by SDS-PAGE.

Formulation

Formulated in a proprietary trehalose-free buffer, supplied ready-to-use for SPR/BLI analysis - no buffer exchange required.

For detailed formulation, please refer to the batch-specific COA.

Background

Interleukin-23 subunit alpha (IL-23 alpha) can associates with IL12B to form the IL-23 interleukin, a heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to a heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.
