简介
Interleukin-12 subunit alpha (IL-12A; IL-12p35), an immune-suppressive cytokine, encodes a subunit of the cytokine IL-12 that acts on T and natural killer cells, and has a broad array of biological activities. IL-12A heterodimerizes with IL-12B to form the IL-12 cytokine or with EBI3/IL27B to form the IL-35 cytokine[1][2]. GMP IL-12 Protein, Human (HEK293), a recombinant GMP-grade protein, is produced in HEK293 cells. It consists of IL-12A and IL-12B.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. 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.

Protein Description
Interleukin-12 (IL-12) is a pivotal cytokine that plays a crucial role in immune regulation and host defense against pathogens and tumors. IL-12 is a heterodimeric protein composed of two subunits, p35 and p40, encoded by separate genes. The p40 subunit, often referred to as IL-12 beta, has garnered significant research interest due to its involvement in immune responses. IL-12 promotes T cell differentiation into Th1 cells, enhances the production of interferon-gamma, and stimulates cytotoxic T lymphocytes and natural killer (NK) cell activity, making it essential for combating intracellular pathogens and malignancies. Dysfunctional IL-12 signaling is implicated in various autoimmune diseases and cancers, further highlighting its relevance in immunotherapy applications. Recombinant IL-12 beta protein has been developed for therapeutic purposes, including cancer vaccines and immune modulation strategies. Studies have demonstrated that delivering IL-12 beta can enhance anti-tumor immunity and improve treatment outcomes in preclinical and clinical settings. Consequently, ongoing research is focused on optimizing the production, delivery mechanisms, and therapeutic efficacy of recombinant IL-12 beta, aiming to harness its potential to improve cancer therapies and address unmet medical needs in immunological disorders.
