Re: PAP pens

From:Kimberly Carter <>

  I use a special barrier slide made by Biogenex. I am not sure about the
availability in the UK. The slides are expensive, but there is never an
issue with  these slides. Biogenex is the company where we bought our
immuno stainer. That is how I became aware of the slides.
