CSF3R/G-CSFR Protein, Human, Recombinant (His 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.

A DNA sequence encoding the extracellular domain (Met 1-Pro 621) of human G-CSF receptor (NP_000751.1) precursor was fused with a polyhistidine tag at the C-terminus.

Measured by its ability to inhibit the GCSF-induced proliferation of NFS60 mouse myeloid cells.The EDfor this ettect is typically 50-250 ng/mL in the presence of 0.125ng/mL of recombinant human GCSF.

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The mature recombinant human GCSFR consists of 608 amino acids and predicts a molecular mass of 68 kDa by SDS-PAGE under reducing conditions, the apparent molecular mass of rhGCSFR is approximately 92 kDa due to glycosylation.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
