Pegylation and microsphere encapsulation extends interferon-alpha activity
Published in Hepatitis Weekly, April 7th, 2003
"Interferon-alpha (IFN) was pegylated and encapsulated in biodegradable microspheres to achieve a long-acting formulation. IFN was pegylated with methoxy-polyethylene glycol (mPEG, MW 2000 or 5000). The conjugation procedures were optimized in terms of concentration of the reactants and the pH condition of the medium," researchers in South Korea reported.
"The conjugates (IFN-mPEG(2000) and IFN-mPEG(5000)) were characterized using SDS-PAGE, size-exclusion-HPLC (SE-HPLC) and matrix-assisted laser desorption and ionization time-of-flight (MALDI-TOF) mass spectroscopy. The...
