G-CSF (granulocyte-colony stimulating factor) is a hormone stimulating the bone marrow to produce more white blood cells. The ligand was developed based on the BAC B.V. technology and specifically screened to bind and elute G-CSF targets in the presence of other proteins from different expression systems. GCSFSelect is an affinity resin designed for the purification of G-CSF (granulocyte-colony stimulating factor) products, enabling high yield and purity in one step. The product is a part of Cytiva's Custom Designed resins program.
