CCR3 is detected with a PE-fluorescence labelled monoclonal antibody. This gating of basophil cells is significantly easier than with any other commercially available BAT.
The cell surface marker of basophils, CD63 is detected by a FITC-fluorescence labeled monoclonal antibody. CD63 is currently the best-validated basophil activation marker directly linked to basophil degranulation.
The first control, anti-FcEpsilonRI, is a highly specific monoclonal antibody binding to IgE receptor. The second control, a tripetide (fMLP) activates the basophils by a non-immunological way.
The CD203c is an other basophil activation marker in addition to the CD63. Our CD203c Reagent Set (RUO) is intended for the use within an extended protocol for the Flow CAST® kit, allowing the measurement of both activation markers, CD63 and CD203c, with two different fluorescence labelled antibodies.
