Product Overview
CAPS (3-(Cyclohexylamino)-1-propanesulfonic acid) Buffer 99% is a high-purity zwitterionic buffer designed for biochemistry and molecular biology applications. Its excellent pH stability (optimal range: 9.7–11.1) and low reactivity with metal ions make it ideal for protein purification, electrophoresis, and enzymatic assays. The 99% purity ensures minimal interference in sensitive experiments, while its high solubility in water allows for easy preparation of buffer solutions. This non-toxic, non-volatile compound is compatible with most lab protocols, providing consistent performance across diverse experimental conditions. Its chemical stability under varying temperatures and resistance to microbial degradation further enhance its reliability in long-term storage. Whether used in research or diagnostic labs, this CAPS buffer delivers reproducible results, reducing variability in critical biochemical processes.
FAQs
1. What is the optimal pH range for CAPS buffer?
CAPS buffer is most effective in the pH range of 9.7 to 11.1, making it suitable for alkaline-sensitive applications.
2. Can this buffer be used with metal ions?
Yes, CAPS has low chelating properties, allowing it to be used in solutions containing metal ions without significant interference.
3. How should CAPS buffer be stored for long-term use?
Store the powder in a cool, dry place, sealed tightly to prevent moisture absorption. Prepared solutions should be refrigerated at 2–8°C.
4. Is this buffer compatible with protein assays?
Yes, its high purity and minimal reactivity make it ideal for protein studies, including electrophoresis and chromatography.
5. What alternatives exist for similar buffering needs?
Alternatives like CHES or AMPSO can be used for high-pH applications, but CAPS offers superior solubility and stability in most cases.
