25x Biotin-detection Ab (human IL-16 Biotin-dAb). PN: B111401B. One vial containing 100 µL of biotinylated anti-human IL-16

Lyophilized Standard Mix-Human Group 3 Panel B, 12-Plex. PN: HG3012B. One vial containing lyophilized recombinant human IL-9, IL-15, IL-16, IL-17C, IL-23p19, IL-24, IL-27, IL-31, IL-32, IL-34, OSM, and SCF.  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-16/LCF.  Can be multiplexed with other analytes in Human Group 3.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) 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 16 (IL-16) is a pleiotropic cytokine that functions as a chemoattractant, a modulator of T cell activation, and an inhibitor of HIV replication. Interleukin-16 stimulates a migratory response in CD4+ lymphocytes, monocytes, and eosinophils and primes CD4+ T-cells for IL-2 and IL-15 responsiveness. IL-16 induces T-lymphocyte expression of interleukin 2 receptor.  IL-16 was originally described as a factor that could attract activated T cells in humans and was previously called lymphocyte chemoattractant factor (LCF). Since then, this interleukin has been shown to recruit and activate many other cells expressing the CD4 molecule, including monocytes, eosinophils, and dendritic cells.
