Re: [Histonet] Species specific antibody marker

From:"Jackie M O'Connor"

Affinity BioReagents, (ABR) has a Mouse MAB (vimentin) which is specific 
for Mouse, Human and Rat. (MA3-745).  You can use this to distinguish 
murine from canine cells, theoretically.  I've used a human mitochondria 
marker to distinguish human from murine - everything that stains is human 
- the ones that don't stain are murine.  This should work the same, I 
would hope.  I haven't found a murine mitochondria marker so far.

        Subject:        [Histonet] Species specific antibody marker

I have received FFPE mouse tissue that has been treated with canine MDCK 
cells. It has been established that there are carcinoma cells present in 
the mice tissue. What I am trying to establish is whether the tumour has 
originated from a canine or murine origin. Does anyone know of any 
immunohistochemical markers that would be species specific for this task?
