Fluorescently labeled UCN is detected in striatal histological sections. Alexa Fluor® 488-labeled-UCN was injected i.p. one hour after unilateral collagenase-ICH. The animals were sacrificed three hours after injection of the labeled-UCN. DAPI (A, D, G, J, & M blue), fluorescently labeled UCN (B, E, H, J, & M green) and total UCN (O, red) were detected by fluorescence microscopy in ipsilateral and contralateral striatum.
