CSF1R protein is ubiquitously found in mononuclear phagocytes, especially macrophages and monocytes, and is involved in a variety of biological processes. It induces the release of proinflammatory chemokines in response to IL34 and CSF1, contributing to innate immunity and inflammation. CSF1R Protein, Human (HEK293, C-His-Avi) is the recombinant human-derived CSF1R protein, expressed by HEK293 , with C-His, C-Avi labeled tag.
