Abstract

Background: Evaluation of bioactivity of recombinant erythropoietin is essential for pharmaceutical industry, quality control authorities and researchers. The purpose of this study was to compare real time RT-PCR and flow cytometry for the assay of biological activity of recombinant erythropoietin.Methods: Three concentrations of recombinant erythropoietin BRP (80, 40 and 20 IU/ml) were injected subcutaneously to mice. After 4 days the blood was collected and used for reticulocyte counts by flow cytometry and also for the RNA extraction. Real time RT-PCR amplification was carried out for b-globin.Results and conclusion: There was a significant correlation between the total RNA amounts (R2= 0.9995), relative quantity of b-globin mRNA (R2= 0.984) and reticulocyte counts (R2= 0.9742) with rhEpo concentrations. Total RNA and quantitative RT-PCR showed significant dose dependent results as well the reticulocyte counts by flow cytometry for the biological activity assay of rhEpo and so these methods could be considered as alternatives for flow cytometry.
