Analysis Note

ControlHuman serum

Application

Immunohistochemistry Analysis: A previous lot was used by an independent laboratory in IH to detect IL-16 in naive kidney tissue (Wang, S., et al., 2008).

Immunocytochemistry Analysis: A previous lot was used by an independent laboratory in IC to detect IL-16 in spinal cord cells (Skundric, D., et al., 2005).

Flow Cytometry Analysis: A previous lot was used by an independent laboratory in FC to detect IL-16 in human PBMCs (McFadden, C., et al., 2007).

Neutralizing Activity Assay: 1–10 µg/mL of a previous lot was used by an independent laboratory at concentrations sufficient to neutralize bioactivity of IL-16 (Morgan, R., et al., 2007).

General description

Originally known as lymphocyte chemoattractant factor (LCF), Interleukin-16 (IL-16) is a product of human peripheral mononuclear cells when antigen-stimulated or mitogen-stimulated. It is also produced by dendritic cells, epithelial cells, eosinophils, fibroblasts and mast cells. The pro-form of IL-16 is a 631 amino acid protein that is cleaved by caspase 3 in activated CD4+ T cells where it is then secreted and is accessible for binding CD4 receptors. IL-16 regulates and induces migratory response in CD4+ lymphocytes, eosinophils, and monocytes. It is a soluble ligand for CD4 and functions to prime responsiveness to IL-2 and IL-15 in CD4+ T-cells. Although Isoform 1's function is thought to be as an anchor to membrane ion channels, Isoform 3 is more widely researched and characterized as component of T-cell cycle progression.

Target description

~20 kDa observed.
Monomers of IL-16 migrate on SDS-PAGE in the range of 17–20 kDa (Zhang, Y., et al., 1998). Active IL-16 (clone 14.1) is detected at ~17 kDa in WB (Skundric, D., et al., 2005).
