Production and Purification of Monoclonal Antibody Against Tumor Marker of TPA
Journal Title: International Journal of Medical Research & Health Sciences - Year 2016, Vol 5, Issue 5
Abstract
Considering the invasive nature of cancer cells, one of the most important and best indicator of them is the markers inside them. One of the most important markers that observed in some types of cancer cells in various parts of the body is the Cytokeratin. Tissue plasminogen activator antigen (TPA) is a Cytokeratin composed of molecules with various molecular weights. The level of TPA serum as associated with cellular growth level and tumorization of cells. In this research, the hybrid of spleen cells in BALB/c female mouse with myeloma cells was conducted with a ratio of 10:1. The resulting monoclonal antibodies were confirmed by SDS-PAGE and western blot. Protein G chromatography was utilized to purify monoclonal antibodies. The results for determining isotypes showed IgM and IgG classes. The titer of the antibody obtained from various clones was capable of identifying Cytokeratin antigen with a dilution of 1/10000. The resulting antibodies were finally confirmed by western blot and all the 5 resulting monoclonal antibodies were capable of identifying a 48 kDa protein. The results indicate that with the help of TPA marker and the monoclonal antibodies produced against them, this marker can be recognized quickly with great accuracy in suspicious cases of cancer. Thus, appropriate measures will be taken to prevent and fight off its probable side effects. This factor can be further used to build a diagonal kit with high sensitivity.
