CellGenix® rh IL-2

GMP and Preclinical grade

CellGenix® Recombinant Human IL-2 reliably activates and expands T cells, natural killer cells (NK cells) and cytokine-induced killer cells (CIK cells). CellGenix® rh IL-2 is produced in our dedicated animal-free GMP facility ensuring maximum safety for optimal use in ATMP manufacturing.

GMP Grade

CellGenix® GMP Recombinant Human IL-2 is produced following applicable GMP guidelines and allows for the safe use in accordance with USP Chapter <1043>, Ph. Eur. General Chapter 5.2.12 and ISO 20399:2022.

Our GMP cytokines are provided with documented evidence of purity, potency, consistency and stability. In combination with our expert regulatory and technical support this will help simplify your raw material qualification and validation efforts.

Preclinical Grade

Designed to meet the demands of translational research, CellGenix® preclinical cytokines are ideal to bridge the gap between the lower quality of research grade and the higher costs of GMP grade materials.

IL-2 Syringe

Our proven CellGenix® GMP rh IL-2 is now available in a liquid format. The single-use syringe is easy to use. It will save you time and avoids handling mistakes – which is especially valuable in a cell therapy manufacturing environment.

You can find more detailed information about the IL-2 syringe in the syringe tab below.

Applications

Interleukin-2 (IL-2) is a cytokine signaling molecule that is mainly produced by T cells. It is a central regulator of immune responses and plays a role in anti-inflammatory reactions, hematopoiesis and tumor surveillance.

IL-2 is used in the cell and gene therapy space to promote proliferation and differentiation of CAR T cells, TCR T cells, Tregs, TILs, NK cells and CIK cells.

Technical Details

Source
Expressed in E. coli
Description

Human IL-2 with a substitution of cysteine-125 by serine, accession # P60568, Pro22-Thr153, N-terminal Met and C-terminal 6xHis-tag, molecular mass 16.3 kDa.

With the exception of the added C-terminal 6xHis-tag, the amino acid sequence corresponds to that of Aldesleukin.

Formulation

Lyophilized from a 0.2 µm-filtered solution containing 25 mM sodium acetate and 50 mM sodium chloride, pH 5.0

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.
