I believe that CYPB1

I believe that CYPB1 expression is constitutive in these tissue types. Are you not getting any EROD activity? or are you comparing different sample types? It may be better to test your EROD assay by inducing CYP1A1 via the aryl hydrocarbon receptor using TCDD, PCB, etc., then, knowing your assay itself is fine, proceed with measuring CYP1B1 activity which is more difficult.
