Name :
Recombinant Human TPO-R Protein (His Tag), HPLC-verified
Biological Activity :
Background :
CD11, also known as c-MPL, is a 635 amino acid transmembrane domain, with two extracellular cytokine receptor domains and two intracellular cytokine receptor box motifs. It is expressed at a low level in a large number of cells of hematopoietic origin. C-MPL is homologous with members of the hematopoietic receptor superfamily. The presence of anti-sense oligodeoxynucleotides of C-Mpl inhibited megakaryocyte colony formation. Thrombopoietin is the ligand for C-Mpl. It was shown to be the major regulator of megakaryocytopoiesis and platelet formation. Defects in c-MPL are a cause of congenital amegakaryocytic thrombocytopenia which is a disease characterized by isolated thrombocytopenia and Megakaryocytopenia with no physical anomalies. Defects in c-MPL also cause thrombocythemia type 2 and myelofibrosis with myeloid metaplasia.

Buffer Solution :
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet.
Shipping :
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.
Redissolution :
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
