RAW264.7 Monocytic Macrophage Leukemia Cells (RAW264.7)

RAW 264.7 is a macrophage cell line that was established from a tumor in a male mouse induced with the Abelson murine leukemia virus. The cells will pinocytose neutral red and will phagocytose latex beads and zymosan. They are capable of antibody dependent lysis of sheep erythrocytes and tumor cell targets. LPS or PPD treatment for 2 days stimulates lysis of erythrocytes but not tumor cell targets.

This cell line is easy to propagate, high efficiency for DNA transfection, sensitivity to RNA interference, and supports replication of murine noroviruses. This cell line is negative for surface immunoglobulin (sIg-), Ia (Ia-) and Thy-1.2 (Thy-1.2). When this line was established, it was described as not secreting detectable virus particles and negative using the XC plaque formation assay. Based on a published study by Dr. Janet W. Hartley in 2008, this line was demonstrated to express ecotropic and polytropic MuLV, and is positive using the XC plaque assay for virus replication
