[Histonet] Bcl-2

[Hannen, Valerie]

Hi everyone,
 
 I am hoping you all can help me solve a problem that I am having with
my Bcl-2 stain. I can get it to stain Follicular Lymphoma tissues, but
for the life of me can not
 
 get normal tonsil tissue to stain.  I use a Retrieval solution with a
pH of 8, use Avidin / Biotin solutions, incubate in the primary for 60
minutes. The tonsil tissues that I 
 
am testing are inhouse fixed and processed tissues. We use Zinc Formalin
for our fixation. Now that I think of it, I am also having trouble
getting a purchased control of 
 
Lymphoma tissue to stain.  The kit that we are using is the Histostain +
kit, and we do our Immuno's manually. 
 
 What am I doing wrong or what am I not doing?  
 
Thanks in advance to any and all replies.
