This lack of interference occurs because steric hindrance of the protonated tertiary amine in HEPES shields the negative charge of DNA to a lesser extent than less substituted buffers. It is commonly used in cell culture media and as an ampholytic separator to create a pH gradient in isoelectric focusing. HEPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It has been demonstrated that HEPES can be used to buffer mammalian cell cultures in closed systems of high and low density cultures, as well as open systems of high density culture and has shown usefulness as a buffer for in vitro fertilization and embryo culture. Registration No 3,257,926) HEPES 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. A user guide for the background, experimental use and technical discussion of GoldBio biological buffers. Since the reported use of HEPES for colloidal gold nanostars synthesis by Xie et al., it has been used in many other seedless methods with varied modifications . HEPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. Choosing the right biological buffer for your experiment can be tricky. It is suitable for use in the bicinchoninic acid (BCA) assay. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. Actual tests may differ. Gold Biotechnology (U.S. HEPES interferes with reactions between DNA and restriction enzymes to a lesser extent than similar buffers with less substituted amine groups, such as Tris. HEPES is one of Good's Buffers and is used in biochemistry and molecular biology. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.8 – 8.2. hepes, nist ® srm ® 2181, RES6003H-B7 HEPES, PharmaGrade, Manufactured under appropriate controls for use as a raw material in pharma or biopharmaceutical production, suitable for cell culture, Printable Buffer Chart - Arranged by Family, Printable Buffer pH Chart - Arranged In Order of pH, How to Pronounce Biological Buffers by GoldBio. HEPES is also used in DNA studies as a buffer solution to form precipitates of calcium phosphate and DNA and as a buffer in electroporation.

HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent; one of the twenty Good's buffers. Gibco HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid ) is a zwitterionic organic chemical buffering agent and is categorized as a "Good" buffer which derives from a set of buffers described by Dr. Norman Good and his colleagues in 1966 (Good et. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.8 – 8.2. The piperazine moiety in HEPES generates nitrogen-centred free radicals that reduce the gold ions (AuC l 4 −), rendering HEPES as both a good weak reducing and capping agent [13,15,16].
