Fyn and Lyn are activated upon SDF-1α stimulation.

Lysates obtained from Jurkat cells unstimulated (0) or stimulated with 100 ng/mL SDF-1α for various time periods were immunoprecipitated with anti-fyn (A) or anti-lyn (B) antibody. The immune complexes were subjected to in vitro kinase reactions. C represents the control antibody.
