Recombinant Human IL-3

Description
Recombinant Human Interleukin 3 (IL3) is a bioactive protein intended for use in cell culture applications. IL3 provides the cytokine connection between the immune system and the hematopoietic system. For example, IL3 supports the proliferation and development of almost all types of hematopoietic progenitor cells and can act as a chemoattractant for eosinophils.
