tract tracing +immuno

[Denis Boire]

I am looking for a retrograde tracer that could be utilized in combination with 
immunohistochemistry which requires a fixation with 5% glutaraldehyde and revealed with 
a peroxidaze reaction. Since so much glut is involved ...fluorecent tracers seem to be out of 
the question. I am condidering cholera toxin B or biocityn and doing a double immuno 
labelling. HRP labelling for neurotransmitter immuno and alkaline phosphatase labelling 
of the tracer. 
Has anyone experience with this combination
