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 IL-20/IL-10D.  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 20 (Accession Q9NYY1) belongs to the Interleukin 10 family and Interleukin 20 cytokine subfamily, which also includes IL-19, IL-22, IL-24, and IL-26. IL-20 is involved in facilitating communication between leukocytes and epithelial cells, thus aiding in tissue repair. IL-20 aides in activating STAT3 in epithelial cells. Interleukin 20 is correlated with inflammatory skin diseases such as eczema and psoriasis. IL-20 has been shown to promote angiogenesis in human tissue samples both in vitro and in vivo.
