Introduction
IL2 is a secreted cytokine that is important for the proliferation of T and B lymphocytes. The receptor of this cytokine is a heterotrimeric protein complex whose gamma chain is also shared by interleukin 4 (IL4) and interleukin 7 (IL7). The expression of this gene in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests an essential role of this gene in the immune response to antigenic stimuli.
Description

Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2µm filtered concentrated solution (1mg/ml) in 20mM PBS, pH 7.4.
Solubility
It is recommended to reconstitute the lyophilized Mouse IL-2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Background
Title: Interleukin-2 Mouse Recombinant: A Key Cytokine in Immunological Research
Abstract:
Interleukin-2 (IL-2) is a critical cytokine that plays a pivotal role in immune responses. This research paper provides a comprehensive analysis of mouse recombinant IL-2, focusing on its production, purification, and applications in immunological research. The paper discusses the significance of IL-2 in immune cell proliferation, activation, and regulatory functions. Furthermore, it elucidates the potential therapeutic implications of recombinant IL-2 in immunotherapy and highlights ongoing research in the field. The information presented in this paper aims to enhance the understanding of mouse recombinant IL-2 and its utility as a research tool in immunological studies.
Introduction:
Interleukin-2 (IL-2) is a cytokine that plays a crucial role in immune regulation, particularly in T cell activation and proliferation. Mouse recombinant IL-2, produced through genetic engineering techniques, enables researchers to investigate its biological functions and therapeutic potential.
Production and Purification:
Recombinant IL-2 is typically produced using expression systems such as bacteria, yeast, or mammalian cells. The protein is then purified using various chromatographic techniques to obtain a highly pure and biologically active form. Quality control measures ensure the integrity and functional activity of the recombinant protein.
Immunological Applications:
Mouse recombinant IL-2 has extensive applications in immunological research. It serves as a potent growth factor for T cells, promoting their proliferation and differentiation. IL-2 also plays a critical role in the development and maintenance of regulatory T cells, which are essential for immune tolerance and homeostasis. Recombinant IL-2 is a valuable tool for studying these processes and dissecting the underlying mechanisms.
Therapeutic Implications:
The immunomodulatory properties of IL-2 have led to its exploration as a potential therapeutic agent in immunotherapy. Recombinant IL-2 has been investigated for its use in cancer immunotherapy, autoimmune disorders, and infectious diseases. Ongoing research focuses on optimizing IL-2-based therapies, including combination treatments and targeted delivery approaches.
Conclusion:
Mouse recombinant IL-2 is a fundamental research tool in the field of immunology. Its production, purification, and applications in immune cell proliferation and regulation contribute to our understanding of immune responses and the development of novel therapeutics. Continued research and advancements in IL-2-based immunotherapy hold promise for improving treatment outcomes in various immunological disorders.
