Lung cancer is the leading cause of cancer-related death worldwide; however, the mechanism of lung carcinogenesis has not been clearly defined. Chronic exposure to hexavalent chromium [Cr(VI)], a common environmental and occupational pollutant, causes lung cancer, representing an important lung cancer etiology factor. The mechanism of how chronic Cr(VI) exposure causes lung cancer remains largely unknown.

In view of OA toxin threat to humans and animals, it is essential to develop a rapid, accurate and sensitive method for the detection and quantification of OA in real samples. In this study, a monoclonal antibody named 10E8 was screened by cells fusion of Sp2/0 with spleen cells isolated from immunized mouse, and the isotype of McAb 10E8 was belonged to IgG1.

Hybridoma technology opened a new horizon in the production of antibodies against target antigens of infectious pathogens, malignant diseases including autoimmune disorders, and numerous potent toxins. However, these clinical humanized or chimeric murine antibodies have several limitations and complexities.

Significantly, their applications in genetics are extensive due to their ceaseless mutational degree, widespread length variations and hypermutability skills. These features make them useful in determining the driving forces of evolution by using powerful molecular techniques.
