Hepes storage temperature

WebExamples of zwitterionic buffers include MOPS and HEPES; Tris and phosphate buffers do not isomerize into zwitterions. Minimal salt effects. In other words, the buffer components should not interact or affect ions involved in the biochemical reactions being explored. Minimal effects on the dissociation from changes in temperature and concentration. http://labs.bio.unc.edu/Salmon/protocolscommonbuffers.html
