Hopax is a manufacturer and supplier of CAPS (CAS 1135-40-6), a zwitterionic biological buffer often used as a buffering agent in biological and biochemical research.


Uses of CAPS Buffer:

  • Cation exchange chromatography
  • Capillary electrophoresis
  • Diffusion blotting and electroblotting
  • In the study of enzymatic processes above physiological pH
  • Used as an effective crystallization solution for different proteins
  • The longer carbon chain of the sulfonic acid group in CAPS gives it a slightly more alkaline range than CHES Buffer (also manufactured by Hopax)


Metal binding: (Compare with other buffers)

  • Negligible metal ion binding.


Solubility in water: (Compare with other buffers)

  • 5g/100ml


Saturation at 0°C: (Compare with other buffers)

  • 0.47 M


Storage:

  • Store at room temperature
