What is the main purpose of using hybridomas in research?

The main purpose of using hybridomas in research is to produce monoclonal antibodies. Hybridomas are created through the fusion of a specific type of immune cell, namely B lymphocytes (which produce antibodies), with a myeloma (cancer) cell that can replicate indefinitely. This fusion allows the resulting hybrid cells, or hybridomas, to have the ability to produce large quantities of a specific type of antibody while also retaining the capacity for continuous growth.

The significance of monoclonal antibodies lies in their specificity; they can bind to a single type of antigen and are invaluable in various fields, including diagnostics, therapeutic treatments, and research applications. For instance, they are used in laboratory tests and for targeting specific cells in treatments for diseases such as cancer.

The other choices, while important in their respective areas, do not pertain directly to the capabilities of hybridomas. Hybridomas are specifically designed for antibody production rather than DNA cloning, stem cell culture, or gene sequencing, which are achieved through different methods and technologies in molecular biology. This specialized function of hybridomas plays a critical role in advancing both scientific research and clinical applications.
