Quantification of a pegylated interferon-alpha2a product by a customised and validated reverse phase-high performance liquid chromatography method.

There is increasing development of pegylated proteins as clinical products for therapeutic interventions in human disease. Quantification of such products relies on appropriately calibrated traditional methods, including reverse phase-high performance liquid chromatography (RP-HPLC). However, currently available pharmacopoeia calibrants, e.
