Hello everyone! I need to label mouse PV inhibitory neurons in the medial prefrontal cortex at an early post-natal time point (P7). However, I am experiencing some problems finding a good antibody to achieve this purpose, since these neurons still do not express PV at this time point (they only start expressing around P14) and I require a strong and, preferably, a nuclear labeling. Can you point me to good antibody for immunohistochemistry in frozen slices?
Thank you in advance for your help.
