IL-5R alpha/CD125 Protein, Human, Recombinant (aa 21-335, His） is expressed in HEK293 mammalian cells with C-6xHis tag. The predicted molecular weight is 45-60 KDa and the accession number is Q01344.

IL-5R alpha/CD125 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-Fc tag. The predicted molecular weight is 70-85 KDa and the accession number is Q01344.

Interleukin-3 receptor subunit alpha, also known as IL-3 receptor subunit alpha, IL-3R-alpha, CD123, and IL3RA, is a single-pass type I membrane protein which belongs to the type I cytokine receptor family and Type 5 subfamily.The specific alpha subunit of the interleukin-3 receptor (IL-3Ralpha, CD123) is strongly expressed in various leukemic blasts and leukemic stem cells and seems to be an excellent target for the therapy of leukemias.
