HumanKine IL-2 demonstrating greater bioactivity and better T cell expansion
Interleukin-2 (IL-2) is a cytokine used for culturing a wide range of leukocytes; inducing proliferation in CD4+ and CD8+ T cells, maintaining normal T regulatory cells function, and is essential in immune homeostasis and self-tolerance.
Proteintech’s HumanKine human cell expressed recombinant IL-2 is up to 40x more active than our leading competitor IL-2 when benchmarked side-by-side in the competitor’s optimized assay protocol. The use of human expression systems in the production of IL-2 ensures that the protein is structurally and functionally optimized for compatibility with the human immune system. This results in a more efficient interaction between Humankine IL-2 and human T cells, leading to heightened bioactivity and increased proliferation rates.

Human Memory/Naïve T Cell Panel for flow cytometry analysis
Characterizing T cell subtypes is critical to optimize methods for T cell expansion during cell therapy developmet. This panel is designed for the separation of T lymphocytes (CD3+) into Helper T Lymphocyte, (CD4+), Cytotoxic T Lymphocyte (CD8+), Naïve T Lymphocytes (CD45RA expressing) and Memory T Lymphocytes (CD45RO expressing). Naïve T cells have not previously encountered an antigen while memory T cells have and can therefore, more quickly respond to subsequent encounters of that antigen.
CD8+ Cytotoxic T lymphocytes (left) and CD4+ Helper T lymphocytes (right) were gated and evaluated for CD45RA and CD45RO expression.
