If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Furthermore, galactose is a fundamental component of the disaccharide lactose and is released through hydrolysis by β-galactosidase enzymes, playing a vital role in the survival and virulence of bacteria. In Escherichia coli, galactose is utilized through the Leloir pathway, with β-d-galactose serving as a carbon source and β-d-galactose inducing UDP-galactose synthesis for biosynthetic glycosylation. Galactose finds applications in researching metabolic disorders like galactosemia and serves as a substrate for enzymes involved in galactose catabolism, making it a valuable component in galactosyltransferase labeling buffer and a supplement in MRS broth for the growth of thermophilic lactobacilli.
Application
- as a supplement in SGal media to grow yeast strains to examine the role of different Ssa heat-shock proteins (Hsp70) isoforms in Hsp90 chaperoning functions
- as a carbon source in Biolog (MT2) microplate assay to test the ability of isolates to utilize carbon substrates
- to induce expression of membrane protein-green fluorescent protein (GFP) fusion in yeast
Biochem/physiol Actions
Features and Benefits
- Ideal for Metabolomics, Biochemical and Cell Biology research

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
