Expression of Kit RNA in mast cells from +/+,Ph/+, Ph/Wsh, andW57/W57 mice. Total RNA prepared from bone marrow–derived mast cells was fractionated by gel electrophoresis and analyzed by blot hybridization. Total cellular RNA (10 mg) was used per lane and hybridization was performed with a Kit cDNA probe. Hybridization with an actin probe is shown below to indicate equal loading.
