Does anyone know of an antibody against cleaved caspase 3, that works in immunofluorescence and was raised in any host, excluding rabbit?

I need to find a good anti-activated caspase-3 to use on brain sections, but it cannot be raised in rabbit so I can contain with another antibody (which is rabbit...). Thank you :)
