Zusammenfassung:The present invention provides an effective High Performance Liquid Chromatography (SE-HPLC) method to separate or resolve the pre-peak, post-peak and main peak of CTLA4-IgG1 fusion protein, where pre-peak resolution is more than 1.3. The invention further provides effective separation and resolution of post peak impurity present in CTLA4 IgG1 protein. Moreover, the present invention also provides the method for the estimation and/or quantification of pre-peak, post-peak and main peak of the protein mixture.
