Penicillinase
Based on 1 Customer Validation
Penicillinase is an enzyme capable of hydrolyzing penicillin. Penicillinase converts penicillin into penicilloic acid, which has no antigenicity, and destroys the antibacterial, antigenic and epileptogenic properties of penicillin. Penicillinase shortens the duration of penicillin-induced seizures and neutralizes the ability of penicillin to form epileptogenic foci. Penicillinase can be used in research related to penicillin hypersensitivity and penicillin-induced encephalopathy.

Description
In Vitro
Penicillinase destroys penicillin in vitro[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Topical administration of penicillinase prevents or eliminates penicillin-induced focal epileptogenic foci in acutely prepared adult cats without altering normal cortical electroencephalographic activity, but it has no effect on strychnine-induced epilepsy[2].
