Interleukin-2 (IL-2) is a cytokine that plays a critical role in regulating the immune system. It is primarily produced by activated T cells and acts as a key mediator of immune responses. IL-2 functions by binding to specific receptors on various immune cells, including T cells, B cells, and natural killer (NK) cells, which triggers a cascade of signalling events that promote the activation, proliferation, and differentiation of these immune cells. Additionally, IL-2 promotes the development and maintenance of regulatory T cells (Tregs), which play a crucial role in immune tolerance and preventing autoimmune responses. IL-2 also supports the differentiation of NK cells, boosting their cytotoxic activity against target cells. In cancer immunotherapy, IL-2 has been used to stimulate the immune system and enhance the antitumor activity of T cells and NK cells. Furthermore, IL-2 has been studied to understand its impact on the development of immunological memory and as a potential adjuvant in vaccine design. The stringent quality control processes behind our PtX™ Human anti-IL-2 antibody ensures optimal performance and reproducibility. Its application potential and reliable performance make it an invaluable tool for scientists, clinicians, and researchers dedicated to advancing immunotherapy, immune regulation, and the understanding of immune-related diseases.

PtX™ | Plant-Based Expression

The biotechnology behind the development and manufacture of this product, transient plant-based expression, effectively turns Nicotiana benthamiana plants into single-use, biodegradable bioreactors. Infiltrating this plant species with Agrobacterium tumefaciens cells, transformed with our proprietary plant expression vectors, allows rapid production of a wide variety of recombinant proteins. Plants are harvested and proteins extracted by various stages of filtration, clarification, purification, and polishing – resulting in a highly functional final product.
