Description

Product Description

HEPES is a zwitterionic organic chemical buffering agent.

Application Notes

HEPES is widely used in many biochemical reactions and as a buffering agent in some cell culture media. It is used in a protein deposition technique in electron microscopy because it did not affect metal substrates.
