CD38 ligation in 32D cells expressing human CD38 induces tyrosine kinase activity.
32D cells were exposed to anti-CD38 (T16) for the times indicated. Cell lysates were separated by SDS-PAGE and transferred to a nitrocellulose membrane, which was probed with the anti-phosphotyrosine antibody 4G10. Molecular mass markers (in kDa) are indicated.
