  • 32 Tests PN: A111182TA. One vial containing 35 µL of anti-human IL-7 conjugated to AimPlex Bead S4P9.

25x Biotin-detection Ab (human IL-7 Biotin-dAb).

  • 96 Tests PN: A111182B. One vial containing 100 µL of biotinylated anti-human IL-7.

  • 32 Tests PN: A111182TB. One vial containing 35 µL of biotinylated anti-human IL-7.

Lyophilized Standard Mix-Human Group 2 Panel A, 10-Plex.

  • 96 & 32 Tests PN: HG2009A. One vial containing lyophilized recombinant human G-CSF, GM-CSF, IFNα2, IL-1α, IL-3, IL-5, IL-7, IL-11, IL-12p40, and IL-13. Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits. 

Application: Optimal antibody pair and antigen standard for assaying human IL-7.  Can be multiplexed with other analytes in Human Group 2.  To be used in conjunction with the AimPlex NR Basic Kit (96 Tests PN: P100001, 32 Tests PN: P100001T) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Interleukin 7 (Accession P13232) is a non-hematopoietic growth factor secreted in the thymus and bone marrow by stromal cells. In lymph nodes, IL-7 plays a crucial role in their organogenesis and is essential for homeostatic proliferation of naïve and memory T cells and involved in B cell differentiation. In both mice and humans, deficiency in IL-7 results in low T cell count, indicating immune deficiency. IL-7 promotes hematological malignancies and elevated levels have been found in the plasma of HIV-infected patients. There may be a correlation between IL-7 expression and depression, when blood fraction and gender are taken under consideration. Effects of IL-7 on cancer cells may promote or arrest growth depending upon the cell type.
