One of our histotech's ran a cyto keratin on our Ventana today.  Our problem 
is that  the keratin stained nicely positive and the smooth muscle stained 
positive also.  We have never had this happen before.  One of the pathologist 
is concerned about carryover.  In the same run was a muscle specific actin.  
He is worried that some of the muscle specific actin was rinsed on to the 
case being stained for keratin.  Any help would be appreciated.  I really 
don't have specifics because I am not at work and I didn't do the run.
