Bioworld BES Buffer, 0.5M, pH 7.5, 250 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.

Daratumumab (PBS) (Anti-Human CD38) is the first-in-class human-specific anti-CD38 monoclonal antibody (IgG1) Daratumumab (PBS) has anti-multiple myeloma (MM) effect Daratumumab (PBS) impairs MM cell adhesion which results in an increased sensitivity of MM to proteasome inhibition[1][2]
Teknova 5M Tris-HCl, pH 8.0. 1000mL, Sterile.
Tris (tris(hydroxymethyl)aminomethane) is used as a component ofbuffer solutions, especially for solutions ofnucleic acids. The useful buffer range for tris (pH 7–9) is similar to the pH of most living organisms. This, and its low cost, make tris one of the most common buffers in the biology/biochemistry laboratory.
