  • Background
    Human Interleukin-7 (IL-7) ELISA Kit (Residue Testing) is based on ELISA sandwich method and designed to detect and quantitative determine of GMP human IL-7 in samples from CAR-T product preparation processing. It contains GMP human IL-7 and a pair of antibodies against the recombinant factor, which are provided by ACROBiosystems. Results are obtained by four parameter logistic curve that were parallel to the standard curves obtained. The verification results indicate that this kit can be used for the quantitative determination of GMP human IL-7 (ACROBiosystems, cat#GMP-L07H24) concentrations. The specificity has been verified.
  • Application

    The Human Interleukin-7 (IL-7) ELISA Kit (Residue Testing) was developed for the detection and quantitative determination of GMP human IL-7 in samples from CAR-T product preparation processing where IL-7 is used as an immunotherapy agent.

    It is for research use only.

  • Reconstitution
    Please see Certificate of Analysis for details of reconstitution instruction and specific concentration.
  • Storage
    1. Unopened kit should be stored at 2℃-8℃ upon receiving.

    2. Find the expiration date on the outside packaging and do not use reagents past their expiration date.

    3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

  • Assay Principles
    This assay kit employs a standard sandwich-ELISA format, providing a rapid detection of IL-7. The kit consists of Pre-coated Anti-IL-7 Antibody Microplate and Human IL-7 Standard and Biotin-Anti-IL-7 Antibody and Streptavidin-HRP and buffers.

    Your experiment will include 6 simple steps:

    a) Bring all reagents to room temperature(20℃-25℃) before use.

    b) Add your sample to the plate and take the Human IL-7 as standard. The samples and standard are diluted by Dilution Buffer.

    c) Wash the plate and add the Biotin-Anti-IL-7 Antibody diluted by Dilution Buffer to the plate.

    d) Wash the plate and add the Streptavidin-HRP diluted by Dilution Buffer to the plate.

    e) Wash the plate and add TMB.

    f) Stop the substrate reaction by adding diluted acid. Absorbance (OD) is calculated by the absorbance at 450 nm minus the absorbance at 630 nm to remove background disturbance before statistical analysis. The OD Value reflects the amount of bound protein.

Typical Data Please refer to DS document for the assay protocol.
 IL-7 TYPICAL DATA

For each experiment, a standard curve needs to be set for each micro-plate, and the specific OD value may vary depending on different laboratories, testers, or equipments. The following example data is for reference only.

  • Background: IL-7
    IL7, Interleukin-7
    Interleukin 7 is also known as IL7, IL-7, and is a hematopoietic growth factor secreted by stromal cells in the red marrow and thymus. It is also produced by keratinocytes, dendritic cells, hepatocytes, neurons, and epithelial cells, but is not produced by lymphocytes. IL-7 stimulates the differentiation of multipotent (pluripotent) hematopoietic stem cells into lymphoid progenitor cells, It also stimulates proliferation of all cells in the lymphoid lineage (B cells, T cells and NK cells). It is important for proliferation during certain stages of B-cell maturation, T and NK cell survival, development and homeostasis. IL-7 is a cytokine important for B and T cell development. This cytokine and the hepatocyte growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. IL-7 binds to the IL-7 receptor, a heterodimer consisting of Interleukin-7 receptor alpha and common gamma chain receptor. IL-7 promotes hematological malignacies (acute lymphoblastic leukemia, T cell lymphoma). Elevated levels of IL-7 have also been detected in the plasma of HIV-infected patients. IL-7 as an immunotherapy agent has been examined in many pre-clinical animal studies and more recently in human clinical trials for various malignancies and during HIV infection. IL-7 could also be beneficial in improving immune recovery after allogenic stem cell transplant.
