Article Snippet: Thus, the secreted CCL5 levels in the media of palbociclib-treated cells and the control cells were assessed by enzyme-linked immunosorbent assay (ELISA) using CCL5 ELISA kit (EK0494, Boster Biological Technology, CA, USA) according to the manual instruction.

Techniques: Blocking Assay, Migration
