D-(-)-Arabinose is used in culture media for some bacteria. It serves as a component of biopolymers such as hemicellulose and pectin. In the synthetic biology laboratory, it is employed as a reversible switch for protein expression under the Pbad promoter (i.e. part of plasmids) in E. coli. Further, it acts as an inhibitor of the enzyme glucose dehydrogenase. In addition to this, it is used as a pharmaceutical intermediate and food additive.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
