Abstract:
【Objective】 To improve method for determinating of biological potency of IgG Fc fragment in Chinese Pharmacopoeia and establish a method which is suitable for enzyme-labeled instrument. 【Methods】 The biological properties of FC fragment of IVIG in Chinese Pharmacopiea(General 3514) was adjusted, including sensitization process, sample treatment and dynamic curve parameters. Meanwhile, the kinetic curve of hemolysis was fitted with Origin, which made the method more suitable for enzyme plate. The biological properties of Fc fragment of IVIG was calculated by kinetics curve reaction of reference and sample. 【Results】 The method are stable, the RSD of repeatability and intermediate is 10%, also with significant improvement in efficiency. 【Conclusion】 The detection of properties of Fc fragment of IVIG is stable and efficient, it can be used for properties of Fc fragment of IVIG.
