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

  • 96 & 32 Tests PN: HG20010. One vial containing lyophilized recombinant human IL-17F, IL-20, IL-21, IL-28A, IL-29, IL-33, M-CSF, MPO, TSLP, and VEGF-A. 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 M-CSF.  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.

Macrophage colony-stimulating factor (Accession P09603) is one of three colony-stimulating factors. M-CSF is essential for homeostasis of macrophages, though combined activity with GM-CSF, IL-3, and IFN-γ may increase macrophage growth from marrow cells. M-CSF also exerts paracrine effects on osteoclasts. It has also been demonstrated that high levels of M-CSF are necessary for normal embryonic implementation and placental development. Overall, M-CSF has a role in modulating many hematopoietic progenitors that affect the processes of immunology, metabolism, fertility, and pregnancy. Clinical studies of M-CSF inhibitors against CSFR1 have demonstrated effects on rheumatoid arthritis and neurodegenerative diseases.
