        Details

        CTGrade GMP rh IL-7 is a recombinant human protein that is produced from E. coli and is designed to support basic, translational, and clinical research, as well as commercial applications, and offers:

        • High biological activity verified by a relevant bioactivity assay
        • Low endotoxin levels
        • ≥ 97% purity
        • High lot-to-lot consistency

        Size: 50 µg, 100 µg, and 1 mg. Custom sizes and packaging available on request.

        IL-7 promotes the stimulation of multipotent (pluripotent) hematopoietic stem cells into lymphoid progenitor cells. IL-7, along with IL-2, 15, and 21, is a member of the common gamma (γc) chain cytokine family.

        • Secreted by bone marrow and thymic stromal cells, dendritic cells, intestinal epithelial cells, hepatocytes, and keratinocytes
        • Signals through its receptor (IL-7R) to promote the differentiation of hematopoietic stem cells into T cells, B cells, and natural killer cells
        • Is a regulator of intestinal mucosal lymphocyte proliferation

        Promotes favorable phenotypes in adoptive cellular therapies such as CAR-T cell therapy when combined with IL-15. The biological activity of CTGrade GMP interleukins and growth factors is standardized, where applicable, to WHO International standards, providing cell and gene therapy developers consistent, lot-to-lot biological activity and performance.

        The CTGrade GMP products are manufactured in a facility that does not use or process beta-lactam containing materials. No animal- or human-derived materials were used during manufacturing or as ingredients. These products are manufactured, tested, and released in an ISO 9001:2015 certified facility following cGMP practices. USP chapter <1043> for ancillary materials has been considered in the manufacture of these products.

        SDS-PAGE Showing a Prominent Band at 17.5 kDa

        Figure 1. CTGrade GMP rh IL-7 (1 μg) was resolved with SDS-PAGE under non-reducing (NR) and reducing (R) conditions and visualized by InstantBlue staining showing a prominent band at 17.5 kDa.

        Cell-Based Proliferation Assay

        Figure 2. The biological activity of CTGrade GMP rh IL-7 was determined in a PHA-stimulated human PBMC cell-based proliferation assay.

        Specifications

        Storage
        This product is shipped at ambient temperature. Immediately upon receipt, store the lyophilized protein at -20°C in a manual defrost freezer.
        Shelf Life
        Unopened vials are stable for 36 months from the date of manufacture as indicated on the label. Reconstituted material should be apportioned in working volumes and stored at or below -20°C in manual defrost freezer. For short term storage reconstituted material is stable for 4-6 weeks when stored at 2-8°C. Stability can be increased by adding at least 0.1% carrier protein.
