The development of such cell line is a lengthy and challenging process. However, cell line with high productivity can be predicted by determining the early markers which will significantly minimize the time required to develop new cell line. This study focuses on the molecular markers in the antibody secretion pathway of a panel of six Chinese Hamster Ovary (CHO) stable cell lines which producing recombinant monoclonal antibodies at different rates, ranging between 2 and 50 pg/cell/day. The correlation between the selected molecular parameters and specific productivity (qp) of the cell lines throughout the exponential phase of batch cultures was studied by analyzing the results statistically using Principal Component Analysis (PCA) in STATISTICA 10. The data was arranged and analyzed according to the cell lines and the days in growth phase of the batch cultures. This study revealed that cell line 47 and cell line 76 had greater influences on the specific productivity than the other cell lines and intracellular heavy chain (HC) showed the strongest positive correlation with the specific productivity of the cell line. Higher intracellular HC is associated with higher specific productivity. More researches on the optimization of the molecular markers especially intracellular HC shall be done to further reveal its correlation with specific productivity. specialized Gan Zun Jia Faculty of Engineering Technology Project Paper (Bachelor Of Manufacturing Engineering Technology (Pharmaceutical) -- Universiti Malaysia Pahang – 2018 Includes bibliographical references Faculty of Engineering Technology Dissertations Universities and colleges Disertations Theses THE0001349(Local) UMP 180531 20251117113403.0 vtls000103695 eng
