Tech Info / Data

Background: 

Recombinant human SCF, expressed in engineered human cells, belongs to the IL-2 protein family. SCF is produced by a variety of cells, such as melanocytes, hepatocytes and bone cells. SCF promotes mast cell development, melanocyte cell survival and proliferation. SCF has been implicated in disease processes characterized by tissue remodeling and fibrosis and acts synergistically in the presence of other cytokines including EPO and GM-CSF.
