Description

CAPS 3-[Cyclohexylamino]-1-propanesulfonic acid
A common "Good Buffer" because it has a pKa value near physiological pH, it is not absorbed through cell membranes, and it is essentially transparent to UV light. It's used for culturing cells in-vitro and other biological applications. CAPS has very low metal-binding constants and is therefore particularly suited to investigate metal-dependent enzymes.

Technical Information:

  • High Purity Grade
  • pKa (20°C): 10.40
  • Ref: Good N.E. et al. Biochemistry 5 467 (1966).
