1. Product Overview and Specifications

CAPSO Sodium Salt (CAS 102601-34-3) is a zwitterionic biological buffer widely used in biochemical and molecular biology research. Key parameters include:

2. Key Applications of CAPSO Sodium Salt

2.1 Biochemical Research

Ideal for enzyme kinetics studies requiring alkaline pH stability (e.g., alkaline phosphatase assays).

2.2 Diagnostic Reagents

Used in blood gas analyzers and immunodiagnostic kits to maintain pH in protein-based solutions.

3. Usage Guidelines and Best Practices

Recommended Concentration: 10–50 mM in aqueous solutions
Temperature Sensitivity: Stable between 4°C–25°C; avoid freeze-thaw cycles
Compatibility: Works with most cations but precipitates in high Ca²⁺/Mg²⁺ concentrations

4. Case Studies: Real-World Applications

4.1 Protein Crystallography

University of Cambridge researchers achieved 1.8Å resolution in lysozyme crystallization using 20 mM CAPSO buffer at pH 9.6.

5. Customer Success Stories

5.1 BioPharma Solutions Inc.

Challenge: Needed pH-stable buffer for monoclonal antibody purification at scale
Solution: Implemented 40 mM CAPSO in affinity chromatography
Result: 92% target protein recovery vs. 78% with previous Tris-HCl protocol

5.2 GeneTech Diagnostics

Improved ELISA test shelf life from 6 to 9 months by replacing carbonate buffer with CAPSO in conjugate stabilization.
