1 µg/lane of GMP-grade Recombinant Human IL-4 (Catalog # 204-GMP) was resolved with SDS-PAGE under reducing (R) conditions and visualized by silver staining, showing a single band at 14 kDa.

GMP-grade Recombinant Human IL-4 (Catalog # 204-GMP) stimulates proliferation of TF-1 human erythroleukemic cell line. The ED₅₀ is typically 0.05-0.2 ng/mL.

MALDI-TOF analysis of GMP-grade Recombinant Human IL-4 (Catalog # 204-GMP). The major peak corresponds to the calculated molecular mass, 15085 Da. The minor peak at 15297 Da is a matrix-associated artifact of the MALDI-TOF.
