HEPES-2-[4-(2-Hydroxyethyl)-1-piperazinyl]-ethanesulfonic acid ≥98% cell culture reagent

Supplier: MP Biomedicals
Description: HEPES is a zwitterionic organic chemical buffering agent; one of the twelve Good's buffers. HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by cellular respiration) when compared to bicarbonate buffers, which are also commonly used in cell culture. Its dissociation decreases as the temperature decreases which makes it a more effective buffering agent for maintaining enzyme structure and function at low temperatures.

HEPES-2-[4-(2-Hydroxyethyl)-1-piperazinyl]-ethanesulfonic acid ≥99% biological buffer

Supplier: Spectrum Chemicals
Description: HEPES, Biological Buffer is as it's name suggests, a buffering agent. It's a zwitterionic organic chemical that is one of the '20 Good's buffers.' Because it's better at maintaining physiological pH despite changes in carbon dioxide, it is widely used in cell culture. It has a decrease of water dissociation with falling temperature, this is especially relevant when working at low temperatures as it maintains enzyme function and structure. That said, it is important when working with HEPES for that particular purpose to keep the HEPES-containing solution in darkness as much as possible
