Corning® EDTA, 0.5M pH 8.0, Corning

Catalog Number: (45001-122)
Supplier: Corning
Description: EDTA (ethylenediaminetetraacetic acid) is a polyamino carboxylic acid. It is a colorless, water-soluble solid and is useful as a chelating agent due to its ability to "sequester" metal ions such as Ca2+ and Fe3+.  These cations are responsible for various undesirable effects in molecular biological and cell culture processes. After being bound by EDTA, these metal ions remain in the solution but exhibit diminished reactivity.  The use of EDTA therefore allows for greater control over many experiments.

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

Supplier: Spectrum Chemicals
Description: HEPES, Biological Buffer, Ultrapure 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
