简介
IL-2R beta (CD122), a type I cytokine receptor expressed on T lymphocytes, is a receptor for IL-2 (Kd: 1 nM approximately)[1]. IL-2R beta mediates T cell immune responses, such as stimulating T cell proliferation and activating lymphokine-activated killer cells[2]. IL-2R beta/CD122 Protein, Canine (HEK293, Fc) is a recombinant canine IL-2R beta (M1-P244) with a C-Terminal hFc tag, which is produced in HEK293 cells.

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.

Protein Description
Interleukin-2 receptor beta (IL-2Rβ/CD122) is a crucial component of the IL-2 receptor complex, which plays an essential role in the modulation of immune responses. This receptor is primarily expressed on activated T cells and natural killer (NK) cells and is involved in mediating the effects of interleukin-2 (IL-2), a key cytokine for T cell proliferation, differentiation, and survival. Research into IL-2Rβ/CD122 has gained prominence due to its implications in various immunological disorders, including autoimmune diseases, cancer, and infections. The receptor exists in different forms, including a high-affinity complex with IL-2Rα (CD25) and a lower-affinity form in conjunction with the common gamma chain (CD132). This diversity allows for fine-tuning of immune responses, making it a target for therapeutic interventions. Recombinant forms of IL-2Rβ/CD122 have been produced for both functional studies and potential clinical applications, including the development of novel immunotherapies. Understanding the structure and function of this receptor is essential for designing effective treatments that enhance immune responses or mitigate excessive inflammation. Thus, the continued exploration of IL-2Rβ/CD122 as a therapeutic target holds promise for advancing strategies to manipulate the immune system in various diseases.
