General Information

Interleukin-21 (IL-21) is a cytokine that plays an important role in humoral and adaptive immune responses. It stimulates the proliferation of NK cells and multiple T cell subsets, especially cytotoxic T cells. It is produced by activated CD4+ T helper cells and NK T cells.

IL-21 is used in the cell and gene therapy space for the ex vivo expansion of T cells, including CAR T cells and TCR T cells and NK cells.

Description

Human IL-21, accession # Q9HBE4, Gln25-Ser155

Formulation

Lyophilized from 200 µl of a 0.2 µm-filtered solution containing 15 mM sodium acetate and 45 mM sodium chloride, pH 5.5

Both product grades are produced under the same conditions in a GMP facility, ensuring an equal product quality and performance. We offer a more comprehensive QC testing including tighter specifications and documentation for our GMP products: Preclinical vs GMP.
