Description
GoldBio’s Carbenicillin (Disodium) EZ Pak™ for 100 mg/mL Solution is a complete antibiotic preparation kit that reduces the prep time, variability, and mess of traditional antibiotic stock prep. This carbenicillin EZ Pak™ includes pre-weighed carbenicillin disodium, a sterile filter, and a sterile container, allowing you to prepare a sterile, accurately concentrated antibiotic solution in minutes, without weighing, calculations, or cleanup.
Carbenicillin is a β-lactam antibiotic commonly used as a more stable alternative to ampicillin for bacterial selection in molecular cloning and protein expression. It provides improved resistance stability by reducing the formation of satellite colonies, helping maintain consistent selection pressure during bacterial growth.
The EZ Pak™ format ensures reliable 100 mg/mL stock solutions every time, making it ideal for busy labs, shared facilities, and when reproducibility and sterility are essential.
Key Benefits
No Weighing or Measuring Required: Pre-weighed antibiotic eliminates the need for a balance and prevents calculation errors.
Fast, Simple Preparation: Add deionized water, filter, and the solution is ready to use.
Improved Selection Stability: Reduced satellite colony formation compared to ampicillin.
Consistent Concentration Every Time: Reliable 100 mg/mL stock improves reproducibility.
Cleaner, Safer Workflow: No antibiotic dust, spills, or cleanup.
Sterile by Design: Built-in filtration supports contamination-sensitive workflows.
