Hu Recom IL-5, ACF, 1000 µg

STEMCELL Technologies Hu Recombinant IL-5 is an animal component-free (ACF) cytokine preparation supplied as a 1000 µg vial for hematopoietic and immunology research. Recombinant human Interleukin-5 supports the survival, proliferation, and maturation of eosinophils from bone marrow or peripheral blood progenitors, making it a standard supplement for in vitro eosinophil differentiation protocols and for studies of allergic airway inflammation, parasitic infection models, and Th2-skewed immune responses. Beyond eosinophil biology, the cytokine is widely used to investigate B-cell class switching toward IgA, mucosal mast cell activation, and downstream JAK2-STAT5 signal transduction in primary leukocyte cultures.

Manufactured without animal-derived raw materials, this ACF formulation supports xeno-free culture workflows and is suited to regulatory-sensitive cell therapy pipelines where traceability of input components is essential. Each vial is shipped frozen and should be stored at -20°C or colder for long-term stability, with single-use aliquots recommended to avoid repeated freeze-thaw cycles. The 1000 µg pack size is well matched to high-throughput screening, routine media supplementation at low ng/mL working concentrations, and multi-batch experimental designs across academic core facilities and industrial immunology laboratories.
