GALE Protein, Human, Recombinant (His)
(Synonyms: UDP-galactose-4-epimerase, SDR1E1) Copy Product InfoSynonyms: UDP-galactose-4-epimerase, SDR1E1
Catalog No. TMPY-03659 Copy Product Info
UDP galactose-4'-epimerase, also known as GALE, enables the body to process a simple sugar called galactose, which is present in small amounts in many foods. Galactose is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas. UDP galactose-4'-epimerase catalyzes two distinct but analogous reactions: the epimerization of UDP-glucose to UDP-galactose, and the epimerization of UDP-N-acetylglucosamine to UDP-N-acetylgalactosamine. Defects in GALE causes epimerase-deficiency galactosemia (EDG), also known as galactosemia type 3. Clinical features include early-onset cataracts, liver damage, deafness and mental retardation.

| Species | Human |
| Expression System | E. coli |
| Tag | N-His |
| Accession Number | Q14376 |
| Construction | A DNA sequence encoding the mature form of human GALE (Q14376) (Met1-Ala348) was expressed with a polyhistidine tag at the N-terminus. Predicted N terminal: His |
| Protein Purity | > 95 % as determined by SDS-PAGE |
| Endotoxin | Please contact us for more information. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM HEPES, 150 mM NaCl, 10% Glycerol, pH 7.5. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | UDP-galactose-4-epimerase, SDR1E1 |
| Research Background |
| Molecular Weight | 40.1 kDa (predicted); 36 kDa (reducing conditions) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
