MOPS is a zwitterionic amino acid which acts as one of the "Good" buffers. Concentrations higher than 20 mM should not be used with mammalian cell cultures.

CAS: 71119-22-7 MDL No: MFCD00064350 Powder Molecular Formula: C₇H₁₄NNaO₄S MW: 231.25 Melting Point: 221° Density (g/mL): 1.41

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…

PIPES is a zwitterionic N-substituted aminosulfonic acid "Good" buffer. Buffers can be made by adding a solution of base to PIPES free acid, titrating to the appropriate pH, or by mixing equimolar solutions of the sesquisodium salt and the disodium salt or dipotassium salt, titrating to…

BES is a zwitterionic buffer that is used in biochemistry and molecular biology research in the pH range of 6.15 - 8.35 for wide applicability to biochemical studies. A protocol has been reported for the use of BES buffered saline in the calcium phosphate mediated transfection of eukaryotic cells…

Tricine was first prepared by Good for use as a buffer for chloroplast reactions. It is structurally similar to Tris, but is much less inhibitory at high concentrations. For ATP assays using firefly luciferase, tricine buffer at 25 mM was found to be the best of ten common buffers tested. …

MES is a zwitterionic buffer. One of the "Good" buffers developed for biological applications. It has the advantages of: midrange pKa, maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pK with temperature chemically and…

Tris is an excellent biochemical and biological buffer for all applications where ultra high purity is required.

Tris and Tris Hydrochloride have been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with…

Borax anhydrous is typically used as a buffer component. The Merck Index lists other uses as: used in the manufacturing of glazes and enamels, a component in tanning agents; curing and preserving skins, an agent used in cleaning compounds, used to artificially age wood, as a preservative, either…

Used as a buffer in biological research. HEPPSO is an efficient separator in protein resolution by IEF. HEPPSO is a Zwitterionic hydrogen buffer.

HEPES is a zwitterionic organic chemical buffering agent. HEPES is widely used in many biochemical reactions and as a buffering agent in some cell culture media.

Tris is relatively non-hygroscopic; however, if needed, Tris Base can be dried at 100°C for up to 4 hours to remove any water. Neither Tris Base or Tris Hydrochloride by themselves provide adequate buffering capacity. Generally the two need to be mixed together to provide a buffer with pH…
