Recombinant Human G-CSFR/CD114 Protein (Fc Tag)

Granulocyte Colony Stimulating Factor Receptor (G-CSFR), also known as CD114, which belongs to the cytokine receptor superfamily, is a cell surface receptor for colony stimulating factor 3 (CSF3) . It is a critical regulator of granulopoiesis. This type I membrane protein has a composite structure consisting of an immunoglobulin (Ig) -like domain, a cytokine receptor-homologous (CRH) domain and three fibronectin type III (FNIII) domains in the extracellular region. Mutations in the G-CSF receptor leading to carboxy-terminal truncation transduce hyperproliferative growth responses, and are implicated in the pathological progression of severe congenital neutropenia (SCN) to acute myelogenous leukemia (AML) . Additionally, autocrine/paracrine stimulation of G-CSFR may be important in the biology of solid tumors, including metastasis.

Measured by its ability to inhibit GCSF-induced proliferation of NFS60 mouse myeloid cells. The ED50 for this ettect is typically 2-20 ng/ml in the presence of 0.125ng/ml of recombinant human GCSF.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
