Basophilic cell migration induced by human recombinant RANTES 10 ng (C) and MCP-1 10 ng (D) into sites of injection. The sections were stained with Toluidine blue (0.1%) and analyzed at a magnification of ×40 (Nikon Diaphore). (A) represents a control and (B) is a positive control where FMLP was used at 10⁻⁶ mol/L. This representative experiment was found to be reproducible and has been performed at least three times.
