Our GMP recombinant proteins are ideal for use in expansion, polarization, and differentiation of cells for research and ex vivo cell processing applications. BioLegend GMP recombinant proteins are also free of BSA or other equivalent carrier proteins, thus eliminating the risk of introducing nonrelated or undesired effects on experiments.

For cell research to have translational potential, the importance of consistent performance and quality in raw materials cannot be overstated. The highly potent bioactivity of our GMP-grade cytokines, such as IL-2, IL-7, IL-15, and IL-21, is verified for each product lot, ensuring consistent quality.

IL-2, IL-7, and IL-15 are among critical growth factors for T cells, playing pivotal roles in T cell-based cancer immunotherapy. Our representative data show that GMP recombinant human IL-2 (left) and IL-7 (center) induce dose-dependent proliferation of cells. Lot-to-lot comparisons, as shown for GMP recombinant human IL-15 (right), demonstrate consistent potency while meeting GMP requirements needed for downstream cell manufacturing.
