I'm greatful and thankful to everyone that have taken their time to help me 
out with the CD31 method.

I have a problem with a post-doc in the lab that wanted me to do CD31 on a 
mouse skin tissue. However, a tech. before be got fired and the hios lab 
notebook cannot be found. In any case, a post-doc wanted to do a direct 
peroxidase staining, because he said it faster and produce less background 
than using a ABC or LSAB2 method. He don't understand about IHC and he 
cannot have an open minded about modification. I have give this post-doc 
every single information from all of you that response to my questions about 
CD31, but he refused to go through with any method, but "direct peroxidase." 
He said that direct peroxidase method is VERY basic and that everyone should 
know and know how to do it (including myself), but why doesn't he, himself 
tell me how it's suppose to work?

My questions, is does anyone know anything about direct peroxidase and how I 
can approached to do CD31? A post-doc asked me to email around and asked all 
of you to show me how to do direct peroxidase for CD31.

I need to talk to my PI about this Post-doc and the rule in this lab, if I 
responsibility is to do histology for everyone in this lab.
