apoptosis essay in dorsal root ganglion tissue

[karl-heinz blenk]

1) I am looking for a marker to detect apoptosis in dorsal root ganglion 
cells using light microscopy.
I con faintly remember having heard something about Acrydyl-orange.
Does anybody has any experience with this substance or any other 
suggestions to offer?

2) Does anyone know wether antibodies to LIF (Leukemia inhibitory factor) 
are available commercially.
I plan to do immunohistochemistry for LIF in neuronal tissue. 

Thank you very much in advance
