Product Description
Oxoid™ Penase is an enzyme (lactamase) derived from Bacillus cereus. It comes as a freeze-dried powder in vials, each containing 3,300 International Units (IU) of activity. When mixed with sterile water, it creates a solution that can break down penicillin-type antibiotics. This is useful in microbiology testing where these antibiotics might interfere with results. The pack contains 10 vials, and each vial is enough for 500 ml of medium.
Applications
- Sterility Testing: Added to culture media to neutralise penicillin in samples, ensuring accurate sterility checks.
- Blood Culture Procedures: Used in blood culture broths to prevent antibiotics from stopping bacterial growth.
- Research & Clinical Labs: For experiments where penicillin needs to be inactivated in samples.
Benefits
- Effective Neutralisation: Quickly inactivates penicillin and similar antibiotics, preventing false results.
- Easy to Prepare: Just add sterile water to reconstitute the powder.
- Stable: Long shelf life (up to 24 months when stored at 2–8°C in freeze-dried form; 4 weeks after reconstitution).
- Reliable: Ensures accurate microbiological testing by removing antibiotic interference.
