Description

Assay (titr.): ≥ 99% | CAS No: 10191-18-1 | Useful pH range: 6.4 – 7.8

Hopax is a manufacturer and supplier of BES (CAS 10191-18-1), a zwitterionic biological buffer, often used as a buffering agent in biological and biochemical research.


Uses of BES Buffer:

  • Researchers have used BES as a binding buffer and eluent in cation exchange chromatography as well as a buffer in gel filtration chromatography.
  • In personal care and cosmetics applications, BES acts as a skin desquamation agent and can protect active ingredients against degradation.
  • This buffer is also commonly used in the diagnostic tests industry.


Concerns:

  • BES interferes with reactions between DNA and restriction enzymes to a lesser extent than similar buffers with less substituted amine groups (e.g.: Tris Buffer), but to a greater extent than other buffers, such as HEPES Buffer, also manufactured by Hopax.
