RE: [Histonet] caspase-3

From:"Jacqui Detmar"

Hi Michele.  I use mouse thymus or spleen controls.  I've done caspase-3
IHC on mouse placenta/uterus and you'll get signals, but the problem
with that tissue is that you tend to have different types of cell death
going on (i.e. non-canonical cell death pathways are triggered that
don't use caspase-3), so it can be confusing to interpret the results.
Also, we have found that active caspase-3 is utilized for signaling
pathways other than cell death, so you might see positives that will
likewise, be confusing.  Mouse lymphocytes die a nice, normal death
 so using thymus or spleen will give you unambiguous results.
Good luck and if you have any further questions, feel free to ask!

A couple questions for those of you doing caspase-3 on animal tissue: Is
it necessary to run a negative control tissue? What is a good positive
control tissue? Will mouse ovary/uterus work?

Thanks in advance for any help with this!
