Real-time PCR amplification of the HMBS and PKC-θ from platelet RNA. (A) The top tracings show the fluorescence recordings using RNA from the patient (arrow) and 3 control subjects. (B) The bars show the ratio of expression of PKC-θ to that of HMBS in the patient and 3 healthy subjects (N). Shown are results (mean ± SE) of 3 separate experiments.
