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.

Interleukin 7 (IL-7) is hematopoietic growth factor secreted by stromal cells in the bone marrow and thymus. It is also produced by keratinocytes, dendritic cells, hepatocytes, neurons, and epithelial cells but is not produced by normal lymphocytes. IL-7 stimulates the differentiation of pluripotent hematopoietic stem cells into lymphoid progenitor cells (as opposed to myeloid progenitor cells where differentiation is stimulated by IL-3).  It also stimulates proliferation of all cells in the lymphoid lineage (B cells, T cells and NK cells).[citation needed] It is important for proliferation during certain stages of B-cell maturation, T and NK cell survival, development and homeostasis. IL-7 promotes hematological malignancies (acute lymphoblastic leukemia, T cell lymphoma). Elevated levels of IL-7 have also been detected in the plasma of HIV-infected patients.
