Interleukin 4 (IL-4) is an anti-inflammatory cytokine and is a key regulator in humoral and adaptive immunity. It has complex biological roles and promotes growth and differentiation of B cells and T cells, and cells of the monocytic lineage.
MACS GMP Recombinant Human IL-4 is designed for
ex vivo
cell culture processing. No animal- or human-derived materials were used for the manufacture of this product, unless otherwise stated in the respective Certificate of Origin. The product is lyophilized without carrier protein or preservatives.

Overview

Interleukin 4 (IL-4) is an anti-inflammatory cytokine and is a key regulator in humoral and adaptive immunity. It has complex biological roles and promotes growth and differentiation of B cells and T cells, and cells of the monocytic lineage.
MACS GMP Recombinant Human IL-4 is designed for

Detailed product information

Background information

IL-4 is predominantly secreted by activated CD4
+
memory and effector T
H
2 cells, basophils, and mast cells. It promotes the proliferation and differentiation of B cells, as well as immunoglobulin isotype switching, and MHC class II antigen and low-affinity IgE receptor expression. Furthermore, IL-4 induces the differentiation of naive CD4
+
T cells into helper T
H
2 cells, while suppressing T
H
1 development, and promotes chemotaxis of mast cells and basophils.

Applications

MACS GMP Recombinant Human IL-4 can be used for a variety of applications, including the
ex vivo
generation of human dendritic cells from enriched CD14
+
monocyte populations.
2–4

Biological activity

  • The specific activity is determined by proliferation assay according to Kitamura
    et al.1
    using TF-1 cells provided by the German Resource Centre for Biological Material (DSMZ). The proliferation assay was calibrated with the international standard for human IL-4 (NIBSC code 88/656) provided by the National Institute for Biological Standards and Control.
  • Minimal specific activity: ≥ 2×

    6
    IU/mg
  • Typical specific activity: ≥ 4.7×
