Background: Erythropoietin, as a principal hormone promotes red blood cell production in bone marrow. Varieties of erythropoietin biosimilar are being produced by recombinant DNA technology in cell cultures. The detection or quantification of these molecules are being performed by diff erent methods which some of theme such as Western blot and enzymelinked immunosorbent assay (ELISA) require sp...

Sir, In patients treated with recombinant human erythropoietin for anaemia of chronic renal failure, pure red-cell aplasia Fig 1. Time course of haemoglobin values and epoetin dose in a patient with anti-erythropoietin antibody induced PRCA.

OBJECTIVE To identify the effect of early parental recombinant human erythropoietin and iron administration on the blood transfusion requirement of premature infants. METHODS In a controlled clinical trial conducted at the neonatal intensive care unit of Al-Hada Military Hospital, Taif, Kingdom of Saudi Arabia over a 16 months period, we assigned 20 very low birth weight infants with gestatio...

The Pichia pastoris expression system was used to produce recombinant human erythropoietin, a protein synthesized by the adult kidney and responsible for the regulation of red blood cell production. The entire recombinant human erythropoietin (rhEPO) gene was constructed using the Splicing by Overlap Extension by PCR (SOE-PCR) technique, cloned and expressed through the secretory pathway of the...

Conditions presently have been established for the high-level expression and simplified purification of recombinant human erythropoietin produced in Spodoptera frugiperda cells. Expression, as mediated by infection with a recombinant baculovirus, was accomplished in suspension culture using reduced levels of serum and media supplements experimentally determined to provide optimum levels of fact...
