[Histonet] kappa/lambda and..

[Mark Tarango]

I"ve seen underfixed tissue stain with an ugly background everywhere for
kappa/lambda (so much that you can't tell what's real staining and what
isn't).  I think it depends on your retrieval.  Especially if you're
digesting for retrieval, and it wasn't properly fixed, I can imagine all
kinds of staining issues.
