I have stained mouse T cells for CCR7 many times, but have heard mixed things about the compatibility of this antibody (clone 4B12, BD). I am also wondering about CCR4 (clone 2G12 biolegend) and CCR5 ( C34-3441, BD). I use the Foxp3/transcription factor staining kit from ebioscience for Foxp3 staining.
I also stain for CCR7 at 37 degrees C - is this necessary for CCR4 and CCR5?
