Immuno for the Kappa/Lambda. As you stated very aptly, I did not use a
completely accurate control as it was not decalcified. I used declere for
antigen retrieval. Do you suggest I try sat. NaOH? If so for how long?
Thanks

Did you do immuno or ISH for the kappa / lambda???? With theses specialy
treated tissues, i.e. decal, the control must have the same treatment to
be accurate . I always match the tissue treatment to the case and here at
the vet school I always match the species as well. Acid treatment will ,
in a sense, be a second fixation and change antigent retrieval times. Did
you use sat. NaOH for retrieval???

Hi fellow listees,
Would decalcification affect Kappa/Lambda staining?  Controls came out
well
but no staining on patient which pathologist insists should have
stained.
The stains were done on a bm core bx which had been decalcified in RDO.
The
T/B cell stains on the same block came out beautiful. Any ideas/thoughts

from you experts? I am just a user!?!
Thanks
