From:"George, Cheryl"

Hi out there,
   We do calretinin on human FFPE tissue and over the last couple of weeks
have had two cases where the patient negative control tissue stains just as
brightly and specifically as the positive.  Other markers on the same
patient tissue don't react this way and I was wondering if anyone has an
idea about what could cause this.  

Thanks in advance!!
