Figure 4From: Disruption of the blood–brain barrier after generalized tonic-clonic seizures correlates with cerebrospinal fluid MMP-9 levels MMP enzyme activity of CSF samples. Top panel: Gelatin zymography gel results. Lane 1: GTC seizure sample; lanes 2 and 3 are controls; lane 4: single GTC seizure sample. Note that only seizure samples had positive MMP activity. (A) The relative optical density of MMP-9. (B) The relative optical density of MMP-2.Back to article page
