چکیده

A simple and efficient MEKC method was developed to simultaneously determine human insulin, its five analogues, the main degradation products and the excipients usually present in injection formulations. A very fast method with a total analysis time of 3 min was then successfully validated for the analysis of human insulin and the quality control of commercial formulations was carried out.

Modeling The Capacity Factor of Analytes in Micellar Electrokinetic Chromatography Using Computational Descriptors

       A multiple linear regression model is proposed to calculate capacity factor of  analytes using structural features computed using HyperChem software. The  chemical descriptors of analytes were computed using HyperChem software and  regressed against the experimental capacity factors of analytes collected from the  literature. The absolute average percentage deviation (AARD) and individua...

Elimination of adsorption effects in the analysis of water-soluble vitamins in pharmaceutical formulations by capillary electrophoresis.

A tendency to an increase in migration times was observed when different water-soluble vitamins were analysed repeatedly in pharmaceutical preparations by capillary electrophoresis. In order to better understand the origin of this effect, the influence of the vitamins and the excipients, such as cellulose derivatives, was investigated. These studies indicated that the increase in analyte migrat...

Development and Validation of a Micellar Capillary Electrophoresis Method for Determination of IFNβ-1b in Lyophilized Formulation of a Biosimilar Product

Human interferons (IFNs) are key cytokines secreted by immune system. They have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. The type IFNs present in humans are α, β and Υ. IFN β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than IFN . Structural properties of I FNs are importan...
