The algae are typically found in the Pacific and Indian Oceans and in the…

Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic, and tribasic (K3PO4). Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH. …

HEPES is a zwitterionic organic chemical buffering agent; one of the twelve Good's buffers. HEPES has been utilized extensively for research and commercial applications in the cell culture and tissue culture industries. HEPES is widely used in cell culture, largely because it is better at…

Boric acid has a single boron; its salt forms complex equilibria in solution, with the ion B4O7-2 being the predominant species. Boric acid is used for weatherproofing wood and fireproofing fabrics; as a preservative; manufacturing of cements, crockery, porcelain, enamels, glass, borates,…

Tris-HCl is an excellent biochemical and biological buffer for all applications where ultra high purity is required. The pH values of all buffers are temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05…

Borax is a salt of boric acid which is used as a buffer. It has a co-complexing ability with other agents in water to form complex ions with various substances. It is also commonly utilized in chromatography and electrophoresis studies. Borax is typically used as a buffer component,…

Sodium dibasic anhydrous is used as a sequestrant, emulsifier and buffer in foods, as mordant in dyeing for weighting silk, in tanning, in manufacturing of enamels, ceramics, detergents, boiler compounds; as fireproofing agent in soldering and brazing instead of borax; as reagent and buffer in…

Sodium phosphate monobasic is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. Useful in conjunction with Sodium Dibasic Phosphate, in the preparation of biological buffers. Used in many applications including the purification of antibodies.

Bis-Tris is a zwitterionic buffer; an amine buffer similar to Tris Hydrochloric acid that exhibits only a very small shift in dissociation constant with respect to temperature. It is structurally analogous to the the Good buffers that were developed to provide buffers in the pH range of 6.15 - 8.35…

MOPS is a zwitterionic amino acid which acts as one of the "Good" buffers. It is a structural analog to MES. However, MOPS is a more suitable biological buffer than MES because the pH range is closer to pH 7.4.

Sodium acetate is the sodium salt of acetic acid. Sodium acetate is used as a buffer in the buffering range of pH 3.6-5.6. It is also used in the purification and precipitation of nucleic acids, protein crystallization, Staining of gels in protein gel electrophoresis, HPLC, mordant dyeing, DNA…

Triethanolamine is a zwitterionic buffer. Triethanolamine(TEA) is used primarily as an emulsifier and surfactant. It neutralizes fatty acids, adjusts and buffers the pH, and solubilises oils and other ingredients that are not completely soluble in water. Triethanolamine is also used as organic…

Tris has 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 carboxylic acids) and…

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…

Bis-Tris is zwitterionic buffer, an amine buffer similar to Tris. It exhibits only a very small shift in dissociation constant with respect to temperature. Hydrochloric acid can be used to adjust pH for a Bis-Tris buffer to the desired pH.

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…
