A characterization of four B16 murine melanoma cell sublines molecular fingerprint and proliferation behavior [PDF]

, 2013
Background: One of the most popular and versatile model of murine melanoma is by inoculating B16 cells in the syngeneic C57BL6J mouse strain. A characterization of different B16 modified cell sub-lines will be of real practical interest.
