Looking for Kappa and Lambda membrane staining in lymphomas in formalin-fixed paraffin embedded human tissue.

We understand that surface staining has been reported.  We have never acheived surface staining in our lymphomas in paraffin sections.  Have you?  Can you please tell me what you use in 1. vendor, 2. catalog #,  3. Dilution, and  4. Pretreatment?
Thank you.
