Life Science Buffers
Bioworld BES (2-(Bis(2-hydroxyethyl) amino) ethanesulfonic acid) Buffer, 0.5M, pH 6.5, 100 mL
Synonym: N,N-Bis(2-hydroxyethyl)-2-aminoethanesulfonic acid sodium salt, BES sodium saltBelongs to the class of Good buffers, as described in the research of Dr. Norman Good et al. (1966), optimized for molecular biology and biochemistry applications.The characteristics of a Good′s buffer include: pKa between 6.0 and 8.0, high solubility, non toxic, limited effect on biochemical reactions, very low absorbance between 240-700 nm, enzymatic and hydrolytic stability, minimal changes due to temperature and concentration, limited effects due to ionic or salt composition of the solution, limited interaction with mineral cations and limited permeability of biological membranes.Technical Information :pKa (25 °C) :7.1 (Free acid)Warning: For laboratory use only.Not fit for agricultural, household, clinical use or human consumption.Appearance: LiquidPH Value: 6.5

Bioworld ACES (N-[carbamoylmethyl]-2-Aminoethane-sulfonic acid) Buffer, 0.5M, pH 6.2, 250 mL
Synonym:N-(2-Acetamido)-2-aminoethanesulfonic acid; N-(Carbamoylmethyl)-2-aminoethanesulfonic acid; N-(Carbamoylmethyl)taurineACES is one ofGood's buffersdeveloped in the 1960s to provide buffers withpHranging from 6.15-8.35 for use in various applications. Azwitterionicbuffer with apKaof 6.9, it is often used as abuffering agentinbiologicalandbiochemicalresearch. ACES had been used to develop buffers for bothagaroseandpolyacrylamide gel electrophoresis.A saturated solution contains 0.22 M at 0°C. ACES binds Cu2+, but not significantly Mg2+, Ca2+or Mn2+.Appearance: LiquidHS Code : 29241900Melting Point: >220 °C (dec.)(lit.)PH Value: 6.0

Bioworld BES Buffer, 0.5M, pH 7.5, 100 mL
Product DescriptionBES (2-(Bis(2-hydroxyethyl) amino) ethanesulfonic acid) buffer has a concentration of 0.5M and a pH value of 7.5. BES is a zwitterionic buffer used in biochemistry and molecular biology, and has been used to study versatile catalyst precursors for mild hydrocarboxylation of alkanes to carboxylic acids. BES was used to determine that saline buffers minimize the action of interfering factors in the bacterial endotoxins test.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
